Again! this is a difficult one! 20 points to the one who gets this correct! 4, 10, 15, 20, 25 which one is the common factor of 25 and 75?

The common factor of 25 and 75 is actually 25. This is because 25 fits into both numbers. 4 doesn’t fit in both. 10 doesn’t fit into both. 15 doesn’t fit into both. And 20 does fit into both. But 25 fits into 25 once and fits into 75 three times

One common factor is 25.

Step-by-step explanation:

4 doesn't divide evenly, and neither does 15 or 20. So 25 is your answer.

(another factor is 5, but that isn't an answer)
