How about: 45
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 greatest common factor of 1925 , 90 = 5
The greatest common factor of 24 , 90 = 6
The greatest common factor of 54 , 90 = 18
The greatest common factor of 90 and 39 is 3
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 greatest common factor of 48 and 90 is 6.
The greatest common factor of 90 and 243 is 9.
The greatest common factor of 99 and 90 is 9.
The greatest common factor of 90 and 130 is 10.
The greatest common factor of 54 , 90 = 18
The greatest common factor of 90 , 77 = 1
The greatest common factor of 1925 , 90 = 5
The greatest common factor of 24 , 90 = 6
The greatest common factor of 90 , 112 = 2
The Greatest Common Factor for 90 and 105 is 15.
Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.Since 18 is a factor of 90, it is automatically the GCF.
