Therefore, GCD of numbers 973, 840, 728, 247 is 1

Given Input Data is 973, 840, 728, 247

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

Prime Factorization of 973 is 7 x 139

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 247 is 13 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(973, 840) = 116760

GCD(973, 840) = ( 973 x 840 ) / 116760

GCD(973, 840) = 817320 / 116760

GCD(973, 840) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 728

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

LCM(7, 728) = 728

GCD(7, 728) = ( 7 x 728 ) / 728

GCD(7, 728) = 5096 / 728

GCD(7, 728) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 247

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

LCM(7, 247) = 1729

GCD(7, 247) = ( 7 x 247 ) / 1729

GCD(7, 247) = 1729 / 1729

GCD(7, 247) = 1

GCD of 973, 840, 728, 247 is 1
