Suji and Sajay went to an orchard and collected some apples to give to their relatives.

Wow! We have
2
collected 24x y red Let us now put them in the
2
apples and 36xy baskets so that each basket
green apples. has the same kind of apples
and is equal in number.

Can you tell me the It will be the HCF of the two
2
greatest number of numbers 24x y and 36xy .
2
apples that we should But I don’t know how to find
put in each basket? the factors of these algebraic
expressions. I need to learn
about them.
