Therefore, GCD of numbers 903, 840, 979, 968 is 1

Given Input Data is 903, 840, 979, 968

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

Prime Factorization of 903 is 3 x 7 x 43

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

Prime Factorization of 979 is 11 x 89

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

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(903, 840) = 36120

GCD(903, 840) = ( 903 x 840 ) / 36120

GCD(903, 840) = 758520 / 36120

GCD(903, 840) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 979

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

LCM(21, 979) = 20559

GCD(21, 979) = ( 21 x 979 ) / 20559

GCD(21, 979) = 20559 / 20559

GCD(21, 979) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 968

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

LCM(1, 968) = 968

GCD(1, 968) = ( 1 x 968 ) / 968

GCD(1, 968) = 968 / 968

GCD(1, 968) = 1

GCD of 903, 840, 979, 968 is 1
