The easiest way to find prime factors is to divide the number by an obvious factor, and then note this down and continue. For instance, 54 is even so can divide by 2 to get 27. 27 has a digit sum of 9, so can divide by 9. This means it has 3 and 3 as prime factors. Divide by 9 and we get 3. That means that the prime factors of 54 are 2, 3, 3, and 3
Do this with 72 and you get 2, 2, 2, 3, and 3.
