The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
The greatest common factor is 2
The GCF is 11.
The GCF of 132 and 198 is 66. The factors of 132 are 2x66=2x2x3x11, The factors of 198 are 198= 3x66=2x11x3x3 The GCF is 66.
You need at least two numbers to find a GCF.
256=2^8, then the factors are 2,22,23,24,25,26,27,28
The factors of 66 from least to greatest are: 1, 2, 3, 6, 11, 22, 33, and 66.
You need at least two numbers to find a GCF.
Factors go in pairs; prime factors are listed least to greatest. 2, 3 and 11
The greatest factors of any positive integers are the numbers themselves. The greatest common factor of 30 and 66 is 6.
The greatest common factor is 2
Since 33 is a factor of 66, it is automatically the GCF.
The GCF is 22.
The factors of 33 from least to greatest are: 1, 3, 11, 33
The GCF is 6.
The GCF is 11.
The factors of 28 are: 1, 2, 4, 7, 14, 28.The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66.The common factors are: 1, 2.The Greatest Common Factor (GCF) is: 2
There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
