210. The greatest common factor (or GCF) is defined as the largest number that can be divided into two (or more numbers) and result in an integer answer (no remainder). To get the GCF, one factors the numbers involved and takes only the factors that both numbers share (the number of times that they are shared). 210 = 2 * 3 * 5 * 7 1260 = 2 * 2 * 3 * 3 * 5 * 7 Factors shared are 2, 3, 5 and 7, so 2*3*5*7 = 210.
You need to find the common factors in rows and columns. You then need to fill in the two numbers in the blank squares that are shared. Finally, you multiply the common factor numbers to find the number.
You need at least two numbers to find a GCF.
What is the greatest common factor shared by 51 and 21?
You need at least two numbers to find a GCF.
That's known as the greatest common factor, or GCF.
The GCF of those numbers is 10 because it is the largest number that goes into both of the other numbers evenly.
There is no common factor for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
A factor is any number, normally an integer, that multiplies by another number or set of numbers to produce the number of which it is a factor. Eg. the factors of 32 are 1,2,4,8,16 and 32. A common factor is a factor that is shared by two numbers, and is commonly use in conjunction with the term "highest common factor", which demands the highest possible shared factor of two numbers. Eg. the common factors of 14 and 21 are 7 and 1.
Oh, what a happy little question! To find the greatest common factor of 80, 90, and 110, we look for the largest number that can evenly divide all three. The greatest common factor of these numbers is 10, which means 10 is like a peaceful little friend that can be shared by all three numbers.
A common multiple
You need at least two numbers to find a GCF.

To find a common factor, you need another number to have common (shared) factor with. However, with any set of numbers, the Least Common FACTOR (the smallest (positive) whole number which divides into each of the numbers without any remainder) will always be 1.
You need to find the common factors in rows and columns. You then need to fill in the two numbers in the blank squares that are shared. Finally, you multiply the common factor numbers to find the number.
The greatest common factor of a number is the largest factor shared between the numbers you're looking at, otherwise known as common. So the factors of 12 are 1, 2, 3, 4, 6, and 12; the factors of 15 are 1, 3, 5, 15; and the factors of 22 are 1, 2, 11, 22. The only common factor here is 1, and is thus the GCF of your three numbers.
GCF (greatest common factor) is the greatest factor shared by two or more numbers. Because you only gave one number, GCF cannot be determined.
