Therefore, GCD of numbers 881, 121, 77, 747 is 1

Given Input Data is 881, 121, 77, 747

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

Prime Factorization of 881 is 881

Prime Factorization of 121 is 11 x 11

Prime Factorization of 77 is 7 x 11

Prime Factorization of 747 is 3 x 3 x 83

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(881, 121) = 106601

GCD(881, 121) = ( 881 x 121 ) / 106601

GCD(881, 121) = 106601 / 106601

GCD(881, 121) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 747

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

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

GCD(1, 747) = 747 / 747

GCD(1, 747) = 1

GCD of 881, 121, 77, 747 is 1
