HCF by Common Division Method


Step 1: arrange the given
numbers in a line in any order.  Example 1: find the HCF of 60
and 72.

Step 2: divide the numbers by

the lowest common prime
number. Write the quotient

below the numbers.


Step 3: then divide the quotients

by the lowest common prime

number.


Step 4: repeat the process till

there are no common prime
numbers to divide by.

Step 5: the product of the
divisors is the required HCF.
