The prime factorization of 30 is 2 x 3 x 5.
27 9,3 3,3,3
The prime factorization of 560 is: 2, 5, and 7
5 x 5 = 25
When all the factors are prime numbers, that's a prime factorization.

A division ladder is a method of finding the prime factors of a number. The number is divided by a prime number. That result is divided by another prime number. This continues until the result itself is a prime number. This result and the divisor from each step are the prime factors of the number. Here are the steps, but not quite the appearance of the division ladder. 108 ÷ 2 = 54 ÷ 2 = 27 ÷ 3 = 9 ÷ 3 = 3 The prime factors of 108 are 2, 2, 3, 3, and 3. Here is an example that better replicates the appearance of a division ladder that goes downward. 2 | 168 ...----- ..2 | 84 .....---- ..2 | 42 .....---- ..3 | 21 .....---- .........7 The prime factors of 168 are 2, 2, 2, 3, and 7.

The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
One way to find the prime factorization of a number is to start with the lowest prime number and see if it evenly divides the number. If it does, check whether the result of the division is divisible by that same prime number. When the prime number you are testing does not evenly divide that number, continue with the next prime number. Continue this until the result of the division is a prime number.Check whether 34 is divisible by 2:34 ÷ 2 = 1717 is a prime number, so the prime factorization is finished.The prime factorization of 34 is 2 x 17.Another way to find the prime factorization of a number is to choose a factor pair for that number. Then, find a factor pair for each of those numbers that is not prime.A factor tree of 34 is34/ \2 17Both 2 and 17 are prime, so the tree is finished.The prime factorization of 34 is 2 x 17.
53 is a prime number so there is no relevant prime factorization for it.
