256=2^8, then the factors are 2,22,23,24,25,26,27,28
The factors of 256 are: 1, 2, 4, 8, 16, 32, 64, 128, 256 The factors of 400 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 The common factors are: 1, 2, 4, 8, 16 The Greatest Common Factor: GCF = 16
You need at least two numbers to find a GCF.
2 and 17
Factors of 256 are 128, 64, etc. Factors of 192 are 96, 64, etc.So greatest common factor is 64.
In the list of common factors, the greatest is the largest, the least is the smallest (which is always 1)
GCF(72, 256) = 8The word "greatest" is a superlative which means that for any set of integers, there can be only one GCF. You cannot have greatest common factors.
There cannot be a greatest common factor (GCF) 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.
The factors of 33 from least to greatest are: 1, 3, 11, 33
The factors of 66 from least to greatest are: 1, 2, 3, 6, 11, 22, 33, and 66.

the factors of 28 from least to greatest are 1,2 and 7
The factors of 256 are: 1, 2, 4, 8, 16, 32, 64, 128, 256 The factors of 400 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 The common factors are: 1, 2, 4, 8, 16 The Greatest Common Factor: GCF = 16
Ascending means to write the factors from least to greatest.
You need at least two numbers to find a GCF.
