That's prime factorization.
45
15,3
5,3,3
655 5,131
The prime factorization.
by using a prime factor tree
44 22,2 11,2,2
2x2x222
51 3,17
48 24,2 12,2,2 6,2,2,2 3,2,2,2,2
I can't draw a factor tree here 76 / 2 = 38 38 / 2 = 19 Prime factorization is 2, 2, 19
The prime factorization of 88 using a prime factor tree is 2 x 2 x 2 x 11.
83 is prime. No tree.
It is: 3*17 = 51
28 14,2 7,2,2
