So the Greatest Common Divisior 491, 656, 356, 611 is 1.

Therefore, GCD of numbers 491, 656, 356, 611 is 1

Given Input Data is 491, 656, 356, 611

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

Prime Factorization of 491 is 491

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 356 is 2 x 2 x 89

Prime Factorization of 611 is 13 x 47

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(491, 656) = 322096

GCD(491, 656) = ( 491 x 656 ) / 322096

GCD(491, 656) = 322096 / 322096

GCD(491, 656) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 356

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

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

GCD(1, 356) = 356 / 356

GCD(1, 356) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 611

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

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

GCD(1, 611) = 611 / 611

GCD(1, 611) = 1

GCD of 491, 656, 356, 611 is 1
