Use a factor tree. 104 52,2 26,2,2 13,2,2,2
Yes because 13*8 = 104
The GCF of 78 and 104 is 26.
factor tree of 216
104 52,2 26,2,2 13,2,2,2
104 52,2 26,2,2 13,2,2,2
I can't make the actual lines, but there's a factor tree. 104 2 * 52 2 * 26 2 * 13 2*2*2*13=104
100 50, 2 25, 2, 2 5, 5, 2, 2
104 8*13 2*4*13 2*2*2*13
208 104*2 26 * 4 13*2 2*2
