The GCF of x and 2x is x.
3 and any multiple of 3 have a GCF of 3. Any two multiples of 3 that differ by 3 have a GCF of 3. I'm not sure how to interpret "twice the smaller number is bigger."
The GCF is 7.
The answer depends on whether or not the prime number is a factor of the other number.If the prime number is a factor of the other number then the GCF is the prime, otherwise the GCF is 1.
GCF of a composite number and a prime number is always 1. Here, 5 is a prime number therefore, gcf is 1.
It is impossible to list the GCF of every pair of numbers, because there are infinitely many numbers. If you are looking for the GCF of any number by itself, the GCF of a single number is that number.
You need at least two numbers to find a GCF.
The GCF of one number is itself. To find the GCF, more than one number is needed.
The GCF is the first number.
20 - 1,2,4,5,10,20 You can not have a GCF of just one number. But written are the factors of 20.
GCF of a prime number and a composite number is 1 if the composite number is not a multiple of the prime number. Here, 5 is a prime number and 108 is a composite number(not the multiple of 5). Therefore GCF of 108 and 5 is 1.
No. The GCF or Greatest Common Factor is the greatest number that divides into both the numbers without remainders. It is at most the smaller of the numbers. 2 does not go into 7 at all. However, 7 divides 7 (once) and 14 (twice), so 7 is the GCF of 7 and 14.
When the first number is a factor of the other, the first number is the GCF.
