First find the prime factors of each: 847= 7 x 11 x 11 91= 7 x 13
Ten less than 847 is 837. You simply subtract 10 from 847 to find the answer.

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. =)

30.25 all you do is 847 divided by 28
7 times 121 = 847
