When you are trying to find the GCF of two numbers and one of the numbers is a multiple of the other, the GCF will be the smaller of the two numbers. The GCF of 3 and 9 is 3.

The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.

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 the smaller number. The GCF of 2 and 4 is 2. The GCF of 3 and 6 is 3. The GCF of 7 and 49 is 7.

To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.

You need at least two numbers to find a GCF. There is no such thing as the GCF of a single number.

Any two integers have a gcf. It is also possible for an odd and an even number to have a gcf other than one; for example, the following numbers (shown in factored form) have the gcf 7: 7 x 7 7 x 8 ex. 3 and 6, the GCF is 3 14 and 21 the GCF is 7

The same as the GCF of 63 and 57, where 57 is the difference of the original two numbers. If you continue this way, you will eventually get one number that is exactly a multiple of the other. In this case, the smaller number is the GCF.
