&lt;pre&gt;
Find the prime factorization of the number
90


We can use factor tree for this 
                              
                               90
                              /  \
                             9 x  10
                            / \   / \
                           3 x3 x 5x2

Therefore the prime factorization of 90 is 3 x 3 x 5 x 2

Notice that 3, 5, and 2 are prime factors. they dont have other factors other than 1 and itself
