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.
The only factor common to all three numbers is... 1
Three only has two factors, one and itself.
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.
