what is the greatest common factor of 864?!?!?!?

Answer 1

Don't you need at least 2 numbers to have a greatest common factor?

anyway,

864 = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Answer 2

I believe that the first respondent is correct. However, if you are looking for the prime factorization of 864, then it would go as follows:

2 x 432
2 x 2 x 216
2 x 2 x 2 x 108
2 x 2 x 2 x 2 x 54
2 x 2 x 2 x 2 x 2 x 27
2 x 2 x 2 x 2 x 2 x 3 x 9
2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

That's it! If you want, you can also show it as:

2^5 x 3^3

Answer 3

you should do this yourself this is called cheating
