Also, any number whose digits sum to a multiple of 3 is divisible by 3. For 51, 5+1=6, and 6 is a multiple of 3, so 51 can be cleanly divided by 3.

51 = 3*17

3*17 = 17 + 17 + 17

17 + 17 + 17 = (10+7) + (10+7) + (10+7)

(10+7) + (10+7) + (10+7) = 30 + 21

30 + 21 = 51

yup, math checks out

This is why I love the number 7. It's the first real prime number. All the others are "first"...1?2?3?5? No, those aren't prime numbers, they're "first" in a long line of not-prime numbers.

Then you get to 7. Is 27943 divisible by 7? If you take away 3 is it? If you add 4 is?

I have no clue, give me 10 minutes or a calculator is the only answer

That's what a real prime number is.

Nobody told her that 100,000,001 is also divisible by 17

Any number where the individual digits add up to a number divisible by '3' is divisible by 3.

51 = 5+1 = 6, which is divisible by three.

Try it, you'll see it always works.

my palms are sweaty

wait till she finds out that 0.99999... 9's to infinity is the same as 1

Math is hard, so I'm just going to assume that's true and move on with my day.

Why did she share this? Does she hate us? I don't even know her.

So is 100,000,001.

I love how every reply has like the opposite energy to the meme. I also find math to be generally awesome.

I don't get it, why is this a big deal?

When you start playing modded minecraft you get really good at multiplying and dividing by 144

Big, if true

I used to do this thing where I would figure out if a number was prime or not and it kept me sane. Realizing this isn't, may have just caused my whole world to fall apart.

Upon closer inspection, yeah. 51 = 17 × 3

= (10 + 7) × 3

= (10 × 3) + (7 × 3)

= 30 + 21 = 51

EDIT: Brackets added.

weird how ppl are getting all excited over this. weirder all the random math facts on the comments. and everyone checking with long math as if it might not be lol. I guess I'll throw a few math facts in?

17 is a prime number. 3 is a prime number.

all numbers can be factored down to primes.

19 is a prime number.

19*3=57. is that one gross too?

This is the only one kind of math that professional darts players will dominate.

I actually really like this. 17 is three less than 20, 20x3 is 60, 3x3 is 9, 51 is 60-9. It just feels nice how it all fits together.

Curse you OP! Why did you post this?

Oh no! 😰

That made my back hurt.

Technically, isn't everything divisible by any number? You just get remainders and/or fractions in the result?

I mean, I still didn't want to know this, but....

Obligatory

17 * 3 baby!

I wasn't that surprised to be honest... but than again, I'm divergent 🤷.
