The only common factor is 1.
The common factors of 10 and 30 are: 1, 2, 5, and 10 Btw, this exact answer was the first response to a google search of "common factors".
The only common factor of those three numbers is 1.
Three only has two factors, one and itself.
The only factor common to all three numbers is... 1
The factors of 4 are 1, 2 and 4. The factors of 5 are 1 and 5. The factors of 10 are 1, 2, 5 and 10. In case you were asking about the first three multiples of 4, 5 and 10, those are 20, 40 and 60.
This question cannot be answered as all three numbers do not share a common factor. 2 has 2 as its only factor 5 has 5 as its only factor 10 has 2 and 5 as its factors. As you can see the three numbers do not contain a common factor, but 10 does have both the other numbers as factors.
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
10, 20, 30.
5 and 10 10 and 15 15 and 20
60,120,180
Factors of 6: 1, 2, 3, and 6. Factors of 18: 1, 2, 3, 6, 9, and 18. Factors of 10: 1, 2, 5, and 10. These three numbers have factors that are common in all of them. Those common factors are 1 and 2. The greatest factor they have in common is 2.
Common factors of 10 and 63 are: 1.
