Prime factorization means writing the composite number as a product of prime numbers only.
Work Step by Step
A prime number has exactly two factors, while a composite number has more than two. Prime numbers: 2,3,5,7,11,13,17,19,,23,29,31,... Prime factorization means writing the composite number as a product of prime numbers Example $42=6\times 7\quad$ ... 7 is prime, but 6 is not, so we write $42=2\times 3\times 7\quad$ ... and we have prime factorization. Example $1300=13\times 100$ $=13\times 2\times 50$ $=13\times 2\times 2\times 25$ $=13\times 2\times 2\times 5\times 5$ (all prime numbers in the product)
