There cannot be a common factor (GCF) of just one number. To be common there need to be at least two numbers.
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
Factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.
The common factors are: 1, 2, 7, 14
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70 The factors of 95 are: 1, 5, 19, 95 The common factors are: 1, 5 The Greatest Common Factor: GCF = 5
1 and 2
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
The common factors of 44 and 70 are: 1 and 2
Since 35 is a factor of 70, all of its factors are common.
1,5,7,35Since 35 is a factor of 70, all of its factors are common.
The common factors of 322 and 70 are: 1, 2, 7, and 14
The common factors of 70 and 105 are: 1, 5, 7, and 35
The common factors of 40 and 70 are 1, 2, 5, 10. 2 and 5 are prime.
The common factors of 40 and 70 are 1, 2, 5, 10
The common factors of 49 and 70 are 1 and 7.
The common factors are: 1, 2
The common factors are: 1, 5
