Take the number 9 and figure out what whole numbers you could multiply together to get that answer. Exclude the numbers and 9. Now take the number 12 and figure out what whole numbers you could multiply to get it. Exclude 1 and 12.
When you're all done, look at them to see what number they have in common. That will be your common factor!
The least common factor of any two or more positive integers is always one (1).
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 12.
Factor out common factors. 9/12 factor out a 3 3*3/3*4 3 as a factor top and bottom, at least once, can be canceled = 3/4 ===================
The least common factor of any set of integers is 1.
Since 9 is a factor of 63, all of its factors are common.
3 is the greatest common factor of 9 and 12.
The least common factor of 9, 12 and 18 is 1.
3 is the greatest common factor of 9, 12, and 24.
Any number can be a common factor. 3 is a common factor of 9 and 12.
The GCF of 9 and 12 is 3. The LCM of 9 and 12 is 36.
The greatest common factor of 60 and 88 is 4.
The greatest common factor (GCF) is: 3.
The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The common factors of 9, 12, and 15 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.

The greatest common factor of 12 and 54 is 6.(12/6 = 2, 54/6 = 9)
The least common factor of any set of integers is 1.
