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.
104 52,2 26,2,2 13,2,2,2
104 52,2 26,2,2 13,2,2,2
100 50, 2 25, 2, 2 5, 5, 2, 2
104 8*13 2*4*13 2*2*2*13
8•13 4•2 2•2•2•13
208 104*2 26 * 4 13*2 2*2
The Greatest Common Factor of 26 and 104 is 26.
Greatest common factor of 39 and 104 is 13.
Factor Tree of 520: ........520 ......../ \ ....104 5 ...../ \ ...4..26 ../\.. /\ 2 2 2 13
The greatest common factor of 38 and 104 is 2.
The greatest common factor of 112 and 104 is 8.
The greatest common factor of 104 and 130 is 26.
