The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Explaining how to find all factors pairs of 40 is easy. All you have to do is find which whole numbers 40 can be divided into.
One way to determine the common factors is to find all the factors of the numbers and compare them. The factors of 15 are 1, 3, 5, and 15. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1 and 5. The greatest common factor is 5.
40,=1,2,4,5,8,10,20 AND 40
Divide 40 by 1, 2, 4 and 5. 1, 2, 4, 5, 8, 10, 20, 40
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24The factors of 32 are: 1, 2, 4, 8, 16, 32The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
The factors for 40 are 1,2,4,5,8,10,20,40 The factors for 50 are 1,2,5,10,25,50

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.
Divide 40 by 1, 2, 4 and 5. 1, 2, 4, 5, 8, 10, 20, 40
You need at least two numbers to find a GCF.
Firstly, a factor of a number is another number that you can divide it by and get a whole number. The factors of 40 are: 1,2,4,5,8,10,20 and 40 The factors of 30 are: 1,2,3,5,6,10,15 and 30 Now, to find the GREATEST common factor of 40 and 30 , we would have to find the biggest number that goes into both 40 AND 30. After reading the factors above, we can see that 10 is the highest number that goes into both numbers, therefore 10 is the greatest common factor of 40 and 30.
The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
