Here are some samples of HCF Using Euclids Division Algorithm calculations.

How to find GCF using Euclid’s Algorithm?

Follow the simple and easy procedures on how to find the Greatest Common Factor using Euclid’s Algorithm. Go through the steps and find the GCF of positive integers a, b where a>b.

Step 1: On applying Euclids division lemma to integers a and b we get two whole numbers q and r such that, a = bq+r ; 0 r < b.

Step 2: If r =0, then b is the HCF of a, b. If r is not equal to zero then apply Euclid’s Division Lemma to b and r.

Step 3: Continue the Process until the remainder is zero.

Step 4: When the remainder is zero, the divisor at this stage is called the HCF or GCF of given numbers.


Find the GCF of 78 and 66 using Euclid’s Algorithm?


Given numbers are 78 and 66

In the given numbers 66 is small so divide 78 with it.

Step 1: On dividing 78 66 you will have the quotient 1 and the remainder 12

Step 2: As the remainder isn’t zero continue the process and take the newly obtained remainder as a small number now.

Thus, 66 12 you will have quotient 5 and remainder 6

Step 3: Since the remainder isn’t zero continue the process and you will get the result as follows

126 where the quotient is 2 and the remainder is zero.

6 is the GCF of numbers as it is the divisor that yielded a remainder of zero.
