Given Input Data is 121, 165, 79, 731

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

Prime Factorization of 121 is 11 x 11

Prime Factorization of 165 is 3 x 5 x 11

Prime Factorization of 79 is 79

Prime Factorization of 731 is 17 x 43

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(121, 165) = 1815

GCD(121, 165) = ( 121 x 165 ) / 1815

GCD(121, 165) = 19965 / 1815

GCD(121, 165) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 79

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

LCM(11, 79) = 869

GCD(11, 79) = ( 11 x 79 ) / 869

GCD(11, 79) = 869 / 869

GCD(11, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 731

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

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

GCD(1, 731) = 731 / 731

GCD(1, 731) = 1

GCD of 121, 165, 79, 731 is 1
