Well you should probably make a tree. So first you have to find out at least the smallest number that goes into 847. 847 goes into 7, which is the smallest, yes. 847 divided by 7 equals 121. 121 goes into nothing only 1. So I think that the prime factor would be 847 and I don't know about the other prime factors. Let me check hold on. Yep that is it. Only 121. Just try to make a tree they help out the best, I think anyway. =)
The greatest common factor of 66 and 847 is 11.
83 is prime. No tree.
61 is already prime. It doesn't need a tree.
When the bottom branch consists entirely of prime numbers.
The common factor of 847 and 1311 is 1.

121
The GCF is 11.
The GCF is 77.
Factors of 385: 1, 5, 7, 11, 35, 55, 77, 385.Factors of 847: 1, 7, 11, 77, 121, 847.GCF (385, 847) = 77

7x2 - 847 [First factor out a 7] 7(x2 - 121) [Now factor it totally] 7(x + 11)(x - 11) x = 11 and -11
First find the prime factors of each: 847= 7 x 11 x 11 91= 7 x 13
IT IS PRIME there is no factor tree
Factor tree of 204
factor tree of 216
