A factor tree of 1575: 1575 / \ 5 325 / \ 5 65 / \ 5 13 Answer: 5*5*5*13 or 13*53
First, look for a factor. The most obvious would be 5, because the number ends in a five, so must be divisible by 5. 65/5 = 13, so the other factor will be 13. So 65 / \ 5 13 and since both 5 and 13 are prime numbers, the tree can't go on any further.
130 = 2 x 65 = 2 x 5 x 13
520 / \ 2 260 / \ 130 2 / \ 65 2 / \ 5 13
65 is a multiple of 13. 13 is a factor of 65. The work is to divide 13 into 65. If the result is an integer, 13 is a factor.
The greatest common factor of 65 and 195 is 65.
