What is the greatest common factor of 10 20 25?

Answer 1

Well, honey, the greatest common factor of 10, 20, and 25 is 5. It's like finding the common denominator at a family reunion - you just gotta look for the biggest number that can divide into all of them without any leftovers. So, in this case, 5 is the lucky winner.

Answer 2

To find the greatest common factor (GCF) of 10, 20, and 25, we first need to find the factors of each number. The factors of 10 are 1, 2, 5, and 10. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 25 are 1, 5, 25. The greatest common factor among these three numbers is 5, as it is the largest number that divides evenly into all three numbers.

Answer 3

25 is not a multiple of 10, so the greatest common factor would not be 10. A lower common factor would be 5, because 10, 20 and 25 all divide by 5, so 5 is the greatest common factor of 10, 20 and 25.
