We find the factors of 40 and 56

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

Then the greatest common factor is 8.

a) What is the greatest number of groups that can be formed?

The greatest number of groups that can be formed is 8 groups

b)How many boys and how many girls will be in each group?
