Therefore, GCD of numbers 661, 242, 39, 911 is 1

Given Input Data is 661, 242, 39, 911

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

Prime Factorization of 661 is 661

Prime Factorization of 242 is 2 x 11 x 11

Prime Factorization of 39 is 3 x 13

Prime Factorization of 911 is 911

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(661, 242) = 159962

GCD(661, 242) = ( 661 x 242 ) / 159962

GCD(661, 242) = 159962 / 159962

GCD(661, 242) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 39

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

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

GCD(1, 39) = 39 / 39

GCD(1, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 911

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

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

GCD(1, 911) = 911 / 911

GCD(1, 911) = 1

GCD of 661, 242, 39, 911 is 1
