First, every number has at a minimum, itself and one as factors (for Prime numbers, these are the only two factors).
Next if you recognize that 40 is even, then 2 is a factor, so divide by 2 to find the quotient of 20. Then 20 can be divided by 2, so another 2 --> 10. 10 divided by 2 is 5, which is prime.
So 40 = 1 x 2 x 2 x 2 x 5. Combinations of these prime factors will also be factors (like 2 x 2 = 4, and 2 x 2 x 2 = 8).

What is the greatest common factor of 10 25 and 40?
The greatest common factor (GCF) of 10, 25, and 40 is 5. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. The factors of 10 are 1, 2, 5, and 10. The factors of 25 are 1, 5, 25. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest factor that is common to all three numbers is 5, making it the greatest common factor.
What are the common factors and greatest common factor of 8 and 40?
Since 8 is a factor of 40, it is automatically the GCF and all of its factors are common.
How To Find all the factor pairs of 40?
The rules of divisibility tell you that 40 is divisible by 1, 2, 4 and 5. Dividing 40 by those numbers gives you 40, 20, 10 and 8. Writing them together gives you the factor pairs of 40. (40,1)(20,2)(10,4)(8,5)
What is the greater common factor of 40 and 30?
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.
