prime factorization is the process of converting a number (like 49 or 30) into prime (numbers divisible by 1 and themselves) factors (2 and 3 are prime factors of 6)
1. 49 --> 7 x 7
well, since 7 is a prime numer, the prime factoriztion of 49 is 7 x 7 (or when you learn the more advanced version, 7 squared)!
2. 30 ---> 15 x 2 (it's best to find a factor that is prime in the first step, like 3 or 2) ---> 2 x 3 x 5 (15 isn't prime)
since 3, 2, and 5 are prime, the answer is 2 x 3 x 5!

49 goes can divide into 7 twice so the prime factorization of 49 is 7,7
30 goes 10 and 3 but ten is not prime so take that and go 2 and 5 the factors all have to multiply to the awnsers and be prime

Break down the number into prime numbers multiplied together.
49 -> 7 * 7
30 -> 2*3*5

prime factorization is where u take it down to parts. like you divide it for the first one it would be 7 times 7 because 7 is a prime number and when dividing it it doest go down any more. for 30 it would be 2 times 3 times 5 because 6 times five is thirty but 6 isnt prime. so u divide it to get 2 times 3 which is. i hope i could help.
