Given Input Data is 968, 847, 215, 490

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

Prime Factorization of 968 is 2 x 2 x 2 x 11 x 11

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 215 is 5 x 43

Prime Factorization of 490 is 2 x 5 x 7 x 7

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(968, 847) = 6776

GCD(968, 847) = ( 968 x 847 ) / 6776

GCD(968, 847) = 819896 / 6776

GCD(968, 847) = 121

Step2:

Here we consider the GCD from the above i.e. 121 as first number and the next as 215

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

LCM(121, 215) = 26015

GCD(121, 215) = ( 121 x 215 ) / 26015

GCD(121, 215) = 26015 / 26015

GCD(121, 215) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 490

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

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

GCD(1, 490) = 490 / 490

GCD(1, 490) = 1

GCD of 968, 847, 215, 490 is 1
