What 2 numbers share a greatest common factor of 15?
15 and 30
Can two even numbers have greatest common factor of 1?
No. Every even number has a factor of 2. So any two even numbers share 2 as a factor. So the greatest common factor has to be at least 2.
What is the largest factor that 2 or more numbers share?
That's known as the greatest common factor, or GCF.
What does it mean to share a common factor?
A common factor of several numbers is a number that can divide evenly into each one of them. '10' is a common factor of 20 and 30. '5' is a common factor of 10 and 15. '3' is a common factor of 6, 9, and 12. '2' is a common factor of all even numbers. '1' is a common factor of all whole numbers.
Is it possible for two numbers to have only one common factor?
Yes. Not counting one as a factor, you could have numbers like 6 and 10 which only share one common factor, 2.
What are the common factors of 2 and 5 and 10?
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.
What 2 numbers share a greatest common factor of 8?
8 and 16 is one possibility.

What is the largest common factor of two or more numbers?
The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 That's the greatest common factor, or GCF.
The greatest common factor of 154 and 198?
You factor out both numbers 154 = 2*11*7198 = 2*11*9Now look and see which factors the numbers share. (2 and 11)Multiply the factors (2*11 = 22)22 is the gcf or greatest common factor
What is the least common factor of 10?
In math, a "common factor" is a factor that two or more numbers share. The least common factor that two or more numbers share is 1. However, 10 is a single number. 10 = 5x2 Hm so I'd say the least common is 5. I just think it gets used much less than 2!
