Finding Prime Factors of Large Numbers | Divisibility Rules | Eat Pi

In this video, I teach you how to find the prime factors of large (big) numbers using common divisibility rules and tests. I go over a factorization problem using the factor tree method.
There's a Pre-Algebra playlist attached at the end of the video if you need help with any other topics.

Doesn't work with 473. 4+7+3 = 14 14 is divisible by 7 which equals 2 but 473 is not divisible by 7 does it only work with 3?

[@Eat_Pi]

Great question, yes that rule is specifically for 3. 4+7+3 = 14 14 is not divisible by 3, so 3 is not a factor. 473 isn't divisible by any number between 2 and 10 but it is divisible by 11. 473/11 = 43 11 and 43 are both prime numbers so those would be your 2 factors 👍

Tysm!i finally get it and i won't fail my test 😁

[@Eat_Pi]

I'm glad I could help, and good luck on your test! 😃 I know you'll crush it you genius 😎

[@dopesponge8430]

What grade

[@phoenix-bb9dk]

Good job sir🗿👌

[@Eat_Pi]

Thanks 😅

[@icantwu]

What about if you have 1332

[@Eat_Pi]

1332 (1332 is divisible by 2) 2 x 666 (666 is divisible by 3) 2 x 3 x 222 (222 is divisible by 2) 2 x 3 x 2 x 111 (111 is divisible by 3) 2 x 3 x 2 x 3 x 37 (all of these are prime numbers, so this would be your answer)

[@theotterworld]

Thanks dude

[@Eat_Pi]

NO PROBLEM YOU FRIGGIN GENIUS! 🥹🤩🥰❤️🦅🔥🐐🐐🐐💯🇺🇲🔥🗽

[@frekynavidaddoctor2999]

I'm a college student and I'm here because our instructor announced that we failed the examination😂

[@Eat_Pi]

Those professors are the worst 😭 I hope the vids are helping, but let me know if you need help or have questions. Good luck 😆

Types of numbers

[@Eat_Pi]

Hi I think this video might be helpful: kzbin.info/www/bejne/aaCbXohno9Z5d9k 👍

[@wcmanii]

None of these videos show me how to do an odd number.

[@Eat_Pi]

What's the number you need help with? I can make a video to show you how to factor it 👍
