A prime number is like 7, you can’t multiply 2 whole numbers to get 7, right? EXCEPT, 1 and 7. So, the two factors are 1 and 7, and that’s it. Another example is 5. It’s only factors are 1 and 5. No other 2 numbers can multiply to 5.

Composite numbers are different. You can multiply something other than 1 and the number to get that number. For example, 12. Some factors are 1 and 12. But more factors could be 3 and 4. OR 6 and 2. Since there are lots of factors equaling 12, it’s composite.

I hope I helped! Tell me if I did. BTW, you can always google “a chart of prime numbers” to see all the primes.

composite numbers are numbers that other numbers can divide evenly into.

8 is composite because 1, 2, 4, and 8 go into it. it has four factors, two of which are not 1 or itself.

2 is not composite because it only has two factors; 1 and itself.

get it?

Do you know what Prime Factorization is ? Or factor trees? I need help doing factor trees
