54 - 1, 2, 3, 6, 9, 18, 27, 54
56 - 1, 2, 4, 7, 8, 14, 28, 56
They each have 8 factors. They have a total of 16 factors together.
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
1 and 2
1 (this is a factor of all numbers) and 2 (since 54 and 56 are both even numbers)
Six factors.
The factors of 54 are:1, 2, 3, 6, 9, 18, 27, 54The factors of 56 are:1, 2, 4, 7, 8, 14, 28, 56The common factors are:1, 2
54 + 56 = 110
2, 6, 18, 54
-54 and -2 aren't technically factors of 108, but they will satisfy this problem.
56 x 54 = 3024
