Factors of 15 are: 1 3 5 and 15 of which 3 and 5 are prime factors
Find 2 factors of 36 first -9 and 4- Now break these factors into smaller factors. That's your prime factorization. 9=3x3 4=2x2 3x3x2x2
In doing the factor tree, you can start with any two factors of the given number. These factors maybe prime or composite. But the resulting factors in the factor tree should always be prime numbers. It means that you have to continue factoring unless you ended up with all prime factors.
