Given Input Data is 980, 245, 488, 931

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 488 is 2 x 2 x 2 x 61

Prime Factorization of 931 is 7 x 7 x 19

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(980, 245) = 980

GCD(980, 245) = ( 980 x 245 ) / 980

GCD(980, 245) = 240100 / 980

GCD(980, 245) = 245

Step2:

Here we consider the GCD from the above i.e. 245 as first number and the next as 488

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

LCM(245, 488) = 119560

GCD(245, 488) = ( 245 x 488 ) / 119560

GCD(245, 488) = 119560 / 119560

GCD(245, 488) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 980, 245, 488, 931 is 1
