Therefore, GCD of numbers 917, 973, 90, 947 is 1

Given Input Data is 917, 973, 90, 947

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

Prime Factorization of 917 is 7 x 131

Prime Factorization of 973 is 7 x 139

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 947 is 947

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(917, 973) = 127463

GCD(917, 973) = ( 917 x 973 ) / 127463

GCD(917, 973) = 892241 / 127463

GCD(917, 973) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 90

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

LCM(7, 90) = 630

GCD(7, 90) = ( 7 x 90 ) / 630

GCD(7, 90) = 630 / 630

GCD(7, 90) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 947

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

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

GCD(1, 947) = 947 / 947

GCD(1, 947) = 1

GCD of 917, 973, 90, 947 is 1
