Therefore, GCD of numbers 811, 272, 49 is 1

Given Input Data is 811, 272, 49

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 811 is 811

Prime Factorization of 272 is 2 x 2 x 2 x 2 x 17

Prime Factorization of 49 is 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(811, 272) = 220592

GCD(811, 272) = ( 811 x 272 ) / 220592

GCD(811, 272) = 220592 / 220592

GCD(811, 272) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 49

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 49) = 49

GCD(1, 49) = ( 1 x 49 ) / 49

GCD(1, 49) = 49 / 49

GCD(1, 49) = 1

GCD of 811, 272, 49 is 1
