Same as with two.
Example: 30, 42 and 60
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 2 x 3 x 5 = 60
Select the common factors.
2 x 3 = 6, the GCF
13, 26 and 39
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
There are no common factors for all three numbers.
The Greatest Common Factor of the three numbers is 6.
The HCF of the three numbers is 100
The greatest common factor for the numbers 3 and 37 is 1.
Any three.
4,8,12
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.
The numbers three and five have the greatest common factor of one.
3
18, 45 & 36
They can be: 18, 36 and 54
13, 26 and 39
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.
One can be a greatest common factor. Though it does not happen often, there are numbers that the only number that they share when factoring is one. An example of this is the numbers two and three. The greatest common factor of two and three is one.
