Therefore, GCD of numbers 798, 152, 79, 981 is 1

Given Input Data is 798, 152, 79, 981

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

Prime Factorization of 798 is 2 x 3 x 7 x 19

Prime Factorization of 152 is 2 x 2 x 2 x 19

Prime Factorization of 79 is 79

Prime Factorization of 981 is 3 x 3 x 109

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(798, 152) = 3192

GCD(798, 152) = ( 798 x 152 ) / 3192

GCD(798, 152) = 121296 / 3192

GCD(798, 152) = 38

Step2:

Here we consider the GCD from the above i.e. 38 as first number and the next as 79

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

LCM(38, 79) = 3002

GCD(38, 79) = ( 38 x 79 ) / 3002

GCD(38, 79) = 3002 / 3002

GCD(38, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 798, 152, 79, 981 is 1
