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

104 8*13 2*4*13 2*2*2*13
The highest common factor of the numbers 104, 348 and 220 is 4.
The GCF of 102 and 104 is 102
13 is a factor of both 78 (6 times) and 104 (8 times).Since 13 is also obviously a factor of itself, it must be the greatest factorthat's common to all three numbers.(If there were a greater one, then 13 would have a factor greater than itself.)
The LCF (least common factor) of any two [positive] integers will always be 1.
