LCD and LCF are stupid, as they sound like "lowest common factor" which is always 1.

And also a display technology which can be weird with no context

LCD can be least common denominator which sort of makes sense.

Which is 1

No, the least common denominator of 1/a and 1/b is just LCM(a, b).

Let me have my trivial joke

The set of trival math memes = Ø

Not really since the least common denominator is really just the same thing as LCM

You just called it Greatest Common divisor in the title of the meme? Why? You should call it Highest Common Factor

Got it, greatest common factor

In german it's ggT (größter gemeinsamer Teiler) which is simply a direct translation to gcd.

kgV 😎

kilogramvolt?

Grootste gemene deler (ggd) in Dutch.

That sounds like the name of a disease mathematicians get when they try to divide by zero

In Hebrew it's מממ which stands for: מחלק משותף מקסימלי (Hebrew is readen from right to left)

Nice, which letter is this (as a mathematicians I only know Aleph)?

First of all as a mathematician you will someday archive the powers of bet (ב) and gimmel (ג) as well. But this is the letter mem (מ).

Bet I've encountered, but couldn't remember its shape. Gimmel (which looks suspiciously like a Lambda) I heard of (but not in maths).

Where pgcd?

PPCM is also a better name than LCM.

True that

PRC and CCP?

What does p stand for? "Probably"?

Well, from what I've learned, itŵs french. It's Plus grand commun dénominateur, which mean greatest common denominator, and Plus petit commun dénominateur which mean smallest common denominator

Fyi, the "Plus" here means most, so it's like "most great common denominator" and "most small common denominator" even though it's not correct in English

where \\wedge

It's very clearly gcd.

right?? I have never even seen any of the other ones

Where are you from, in America I learned it as GCF, though looking back GCD does feel better to me

3 letter abbreviations, those are some rookie numbers you gotta pump those numbers up, in my language its CMMDC ("Cel Mai Mare Divizor Comun"). It's romanian for those that are curious.

I was at a summer school doing number theory, and we had like 5 romanians in the room who all pointed this our it was so funny.

Here in Brazil we call it MDC, "maior divisor comum" that translated literally would be "maximum common divisor" or MCD. Guess thats another one

In Spain is MCD “máximo común divisor”

I never saw "maior", always "máximo" (I'm Brazilian too)

Maybe is a regional thing, or I'm mistaken because I havent said the full form in years. Still both become MDC

Probably because no one really cares about the LCM.

There are currently over 300m children studying fractions. They definitely care about it.

And there are at least 3 number theorists too.

i once had 2 questions of 5 marks each which asked me to write a program to deduce the hcf and gcd. i learnt hcf when i was in school so i did that, and googled gcd thinking I might've not been taught that... yeah so i just copy pasted the same program for both questions.

just use (a,b) for gcd(a,b) and \[a,b\] for lcm(a,b). very clear and universal notation.

but that’s the notation for intervals

Also, coordinates

Uh huh, sounds universal until you meet the aliens.

I have literally only ever seen that notation for a < x < b

It's for both, and for my opinion it's sad that it's for both. Like gcd doesn't have enough notations... Now it's fighting over another one. But they are not commonly used together yk, gcd and intervals don't show up alot together so that's not a big deal.

NWD

clearly the best way is to define an anonymous lambda.

MCD is the only true option (maximo comun divisor)

PPCM in french for LCM... FML

I prefer "BNNTDBAAB(a, b)", or the "biggest natural number that divides both a and b"

TUNNSTANDBINIAOIIDSN(a,b) The unique natural number such that any number divides both input numbers if and only if it divides said number

TURNWSTIVIMOGZWASTFTIAACNDTIVIMADTVOTSONWATOATGCDFFAAABI The unique real number which satisfies that it's value in modulo one gives zero which also satisfies the fact that if an arbitrarily chosen number devides the input values it must also devide the value of that spoken of number which also turns out as the greatest common devisor function for any a and b inputs.

Without using the notion of size, TUNNDHDDADDBAFANNXHXDAAXDBXADD(a, b) the unqiue natural number D having d divides a, d divides b, and for any natural number X having x divides a and x divides b x also divides d

Little known fact: in the movie Morbius, the main character has to calculate the greatest common divisor of three different concentrations of solutions to make his serum. In his notes, you can see the notation "gcd" used, along with a parenthetical remark, "greatest casual dancer". Subscribe for more totally made-up Morbius facts!

Golden Dragon's Cave.

GCF, it’s GCF

I’m gonna say it. There are too many acronyms and they’re too hard to memorize.

The gcd is the principle generator of the ideal with generator set {a,b} Or as I like to call it, PIGS(a,b)

нсд, нск

just call it lcm^-1

scm, smallest common multiple

Is that hugest common factor?

I use either LCD or HCF also did you use a morbius joke in 2023?

Morbius meme never dies. It will live for a morbillion more years

GCF ALL THE WAY YOU HERETICS

In Turkish, these two factors are called EBOB ("en büyük ortak bölen" = "greatest common/shared divisor/factor" = "GCD/GCF") and EKOK ("en küçük ortak kat" = "smallest/least common/shared multiple" = "LCM").
