Therefore, GCD of numbers 220, 747, 79, 811 is 1

Given Input Data is 220, 747, 79, 811

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 79 is 79

Prime Factorization of 811 is 811

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(220, 747) = 164340

GCD(220, 747) = ( 220 x 747 ) / 164340

GCD(220, 747) = 164340 / 164340

GCD(220, 747) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 220, 747, 79, 811 is 1
