The prime factorization of 45 is 3 x 3 x 5 or 3^2 x 5 in exponential form.
The prime factors of any number are found by repeated division by primes until a quotient of 1 is obtained. We only take note of those divisors which divide into the number evently.
45 divided by 3 = 15
15 divided by 3 = 5
5 divided by 5 = 1
So, all the divisors which evenly divided into the number must be assembled and become the prime factors - in this case, the prime factors of 45 are 3, 3 and 5.
