5 / 6
The only common factor is one.
1, 2, 7 and 14 go into 14. 1, 5, 7,and 35 go in to 35. 14 and 35 have no common factors (whole numbers)
The only common factor of 14 and 35 is 7 and 1 because only these numbers go into both 14 and 35.
The numbers that go into 35 are 1, 5, 7,and 35
The numbers that go into both 21 and 35 are their common factors. The factors of 21 are 1, 3, 7, and 21, while the factors of 35 are 1, 5, 7, and 35. The only common factor between them is 7. Thus, 7 is the greatest common divisor of 21 and 35.
The common factors are: 1, 7
The common factors of 175 and 245 are 1, 5, 7, 35.
The common factors are: 1, 2, 4, 8
In the absence of the numbers below, let's go with 24 and 48.
The common factors are: 1, 2, 3, 6.
