They are: 8 minus 4 = 4
The factors of 4 are: 1, 2, 4 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
We won't be able to find factors of 80 that are not factors of 80. The factors of 80 that aren't factors of 42 are 4, 5, 8, 10, 16, 20, 40 and 80.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.Factors of 4: 1, 2, 4.GCF (80, 4) = 4
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 Those which are multiples of 4 are: 4, 8, 16, 20, 40, 80
The common factors are: 1, 2, 4
The common factors of 36 and 80 are: 1, 2, and 4
The common factors of 68 and 80 are 1, 2 and 4.
The factors of 16 are: 1, 2, 4, 8, 16 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.
It should be clear here that the answer is 4 (it cannot be greater than the difference of the numbers). In general you list the factors of each: 80 has factors 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 84 has factors 1, 2, 3, 4, 7, 12, 21, 28, 42, 84 And pick the biggest number which here is 4.
Factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.Prime factors = 2, 5.
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
