Question from ashi, a student:

the student of three classescan be made to stand into rows having same number of students. there are 24,36 and 60 students in the classes. how many maximum number of student will stand in each row.

Hi Ashi.

If each class has a whole number of rows and every row is the same size, then the number of students in each row must be a divisor of all three numbers. If you are looking for the maximum number of students in such a row, then you are looking for the greatest common divisor (GCD).

What is the largest number that goes into 24, 36, and 60?

Hope this helps,
Stephen La Rocque.
