Therefore, GCD of numbers 981, 477, 13, 973 is 1

Given Input Data is 981, 477, 13, 973

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

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 13 is 13

Prime Factorization of 973 is 7 x 139

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(981, 477) = 51993

GCD(981, 477) = ( 981 x 477 ) / 51993

GCD(981, 477) = 467937 / 51993

GCD(981, 477) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 13

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

LCM(9, 13) = 117

GCD(9, 13) = ( 9 x 13 ) / 117

GCD(9, 13) = 117 / 117

GCD(9, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 973

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

LCM(1, 973) = 973

GCD(1, 973) = ( 1 x 973 ) / 973

GCD(1, 973) = 973 / 973

GCD(1, 973) = 1

GCD of 981, 477, 13, 973 is 1
