There are 72 boys and 90 girls on the Math team For the next math competition Mr Johnson would like to arrange all of the students in equal rows with only girls or boys in each row with only girls or boys in each row. What is the greatest number of students that can be put in each row?
To find the maximum number (n) of boys or girls in each row, we want the GCF (Greatest Common Factor) of 72 and 90.
Using our GCF calculator for GCF(72,90), we get 18.

- 72 boys divided by 18 = 4 rows of boys
- 90 girls divided by 18 = 5 rows of girls
