It is: 2*2*2*2*2*2 = 64 or as 26 = 64
The prime factors of 86 are 2 and 43
As a product of its prime factors: 2*2*2*3*5 = 120
470 Divide by two. 235,2 Divide by five. 47,5,2 Stop. All the factors are prime.
2 and 13 are the prime factors and the other factors are 1 and 26
145 5,29
The prime factors of 86 are 2 and 43
As a product of its prime factors: 7*7*13 = 637
As a product of its prime factors: 2*3*13 = 78
As a product of its prime factors: 2*2*2*3*5 = 120
The prime factorization.
That's a lot of extra work for this problem but here goes. 3 is already prime so it doesn't really have a factor tree or prime factorization. The prime factorization of 4 is 2 x 2 which looks like this in a factor tree.42,23 and 4 have no common prime factors, so the LCM is their product, 12
470 Divide by two. 235,2 Divide by five. 47,5,2 Stop. All the factors are prime.

1997 is already prime; no tree.
139 is already prime; no factorization required.
