Question

Find the greatest number that divides $306,450$ and $540$ completely.

Answer 1

Finding the H.C.F. (greatest number that divides the given numbers) of two numbers $306$ and $450$.

We can find the H.C.F of $306$ and $450$ such that:

so, the H.C.F of $306$ and $450$ is$18$.

Finding the H.C.F. of $18$ and $540$.

We can find the H.C.F of $18$ and $540$ such that:

so, the H.C.F of $18$ and $540$ is $18$.

Hence, the H.C.F of $306,450$ and $540$ is $18$.
