Factors that are the same for two or more numbers are their common factors.
What numbers are factors of both 7 and 8?
Factors of 7 are 1, and 7.
Factors of 8 are 1, 2, 4, and 8.
Common factors are the numbers that are in both lists.
So, 1 is the common factor of 7 and 8.
Just 1.
6, 7, and 8 share no common factors aside from 1.
It is one.
No, it is in its simplest form as there are no common factors for 7 and 8
factors of 7 = 1, 7 factors of 8 = 1, 2, 4, 8 common factor between 7 & 8 is 1. Therefor, GCF of 7 & 8 = 1
The factors of 35 are:1, 5, 7, 35 The factors of 56 are:1, 2, 4, 7, 8, 14, 28, 56 The common factors are:1, 7 The Greatest Common Factor:GCF = 7
The factors of 7 are:1, 7The factors of 8 are:1, 2, 4, 8The factors of 11 are:1, 11The common factor is:1
The only common factor is 1.
7 is a prime number, and not a factor of 8 or 9. 1, 2, 4, and 8 are factors of 8. 1, 3, and 9 are factors of 9. 7, 8, and have no common factors. So the least common multiple of 7, 8, and 9 are 7 X 8 X 9, which equals 504504
The common factors of 40 and 56 are: 1, 2, 4, and 8
As factors, only 1.
The factors of 63 are 1,3,7,9,21, and 63 The factors of 56 are 1,2,4,7,8,14,28 and 56. The factors that are shared are 1 and 7. So the common factors of 63 and 56 are 1 and 7.
Because 7 is a prime number, its only factors are 1 and 7. 7 is not a factor of 4 or 8, so 1 must be the only factor common to all four numbers. To work it out in detail: Factors of 4: 1 2 4 Factors of 7: 1 7 Factors of 8: 1 2 4 8 Factors of 14: 1 2 7 14 The GCF of 4, 7, 8, and 14 is 1
