Therefore, GCD of numbers 49, 392, 811, 212 is 1

Given Input Data is 49, 392, 811, 212

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 811 is 811

Prime Factorization of 212 is 2 x 2 x 53

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(49, 392) = 392

GCD(49, 392) = ( 49 x 392 ) / 392

GCD(49, 392) = 19208 / 392

GCD(49, 392) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 811

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

LCM(49, 811) = 39739

GCD(49, 811) = ( 49 x 811 ) / 39739

GCD(49, 811) = 39739 / 39739

GCD(49, 811) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 212

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

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

GCD(1, 212) = 212 / 212

GCD(1, 212) = 1

GCD of 49, 392, 811, 212 is 1
