Four common factors.
Common factors of 10 and 20 would be 1, 2, 5, and 10.
The common factors of 20 and 60 are: 1, 2, 4, 5, 10, and 20 The common factors of 20 and 60 are: 1, 2, 4, 5, 10, and 20.
They can be. 4 and 10 are common factors of 20 and 40.
The factors of 10 are 1, 2, 5, and 10. The factors of 20 are 1, 2, 4, 5, 10, and 20. Common factors of 10 and 20 are 1, 2, 5, and 10. 1,2,5,10. 1, 2, 5 and 10.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
the factors of 5 are 1 and 5the factors of 20 are 1 2 4 5 10 20the factors of 45 are 1 3 5 9 15 45so the common factors are 1 and 5
The GCF of 20 and 10 is 10.
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
The factors of 10 are: 1, 2, 5, 10.The factors of 15 are: 1, 3, 5, 15.The factors of 20 are: 1, 2, 4, 5, 10, 20.The common factors are: 1, 5.
Since 10 is a factor of 20, all of its factors are common.
The common factors are: 1, 5.
