1 and 5
The common factors of 20, 25, and 40 are 1 and 5.
Factors of 20: 1, 2, 4, 5, 10, 20Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80Common factors of 20, 30, and 80: 1, 2, 5, 10
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50 and 100. For them to be common, they need to be compared to another set of factors.
1 and 5, the GCF.
The common factors of 25 and 50 are 1, 5 and 25.All of them.
Common factors for 20 & 25 are: 1 & 5
Common factors of 20, 25, and 40 are: 1 and 5.
The greatest common factor of 20 and 25 is 5:The factors of 20 are 1, 2, 4, 5, 10 and 20.The factors of 25 are 1, 5, and 25.The common factors of 20 and 25 are therefore 1 and 5 (and 5 is, of course, the highest).The HCF is: 5
The common factors are: 1, 5
The answer to the question is: "All of the common factors of 10, 25, and 20 are 1 and 5 ."
The common factors are: 1, 5.
The factors of 25 are 1, 5 and 25. For them to be common, they need to be compared to another set of factors.
The common factors of 20, 25, and 40 are 1 and 5.
