Factors of 40: 1,2,4,5,8,10,20,40 1 x 40 2 x 20 4 x 10 5 x 8 Factors of 30: 1,2,3,5,6,10,15,30 1 x 30 2 x 15 3 x 10 5 x 6 Common factors: 1, 2 5, 10 10 is the highest common factor.
The common factors of 30 and 40 are: 1, 2, 5, 10.
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.
