6 and 9
.54 × 120 = 64.80
-1, 6 and -12.
-54 and -2 aren't technically factors of 108, but they will satisfy this problem.
-10 and 2 -12 and 4 -20 and 12
15 and 4 are the factors of 120 that add up to 19.
40 and 3, if you add them.
6 and 9
Factors of 120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.Factors of 78: 1, 2, 3, 6, 13, 26, 39, 78.Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54.GCF (120, 78, 24, 54) = 6
120-54 = 66
.54 × 120 = 64.80
146
-1, 6 and -12.
How about: 9+6 = 15
120/100 gives you 1%=1.2 54/1.2 = 45 which is the percentage of 54/120

Add up its proper factors. If that sum is less than 54, it's deficient.
