3 times 5
Prime numbers don't factorize; they're already prime.
Prime factor means the factors of the number which divides the number. Example :- 15= 3× 5 . Here the 3 and 5 are the prime factors of 15. Prime factors of 74 - 2×37.
You can use prime numbers to factorize numbers, a very useful tool
break it into prime number multiples,10 = 2 * 5 (both prime numbers)example: factorize 387(387) = 9 * 43 (both primes , end of excercise)factorize 390:(390) = 2 * (195) = 3 * (65) = 5 * 13 (both primes , end of excercise)
You can use prime numbers to factorize numbers, a very useful tool.
2 x 2 x 3 x 19 = 228
The prime factorizationof 99 is 3 x 3 x 11.
2 x 2 x 2 x 2 x 2 = 32
-13
The prime factorization of 57 is 3 x 19 = 573*19

Sorry wasnt allowed to use punctuation. I mean 3X*2 - 15
