Therefore, GCD of numbers 903, 637, 857, 658 is 1

Given Input Data is 903, 637, 857, 658

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 637 is 7 x 7 x 13

Prime Factorization of 857 is 857

Prime Factorization of 658 is 2 x 7 x 47

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, 637) = 82173

GCD(903, 637) = ( 903 x 637 ) / 82173

GCD(903, 637) = 575211 / 82173

GCD(903, 637) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 857

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

LCM(7, 857) = 5999

GCD(7, 857) = ( 7 x 857 ) / 5999

GCD(7, 857) = 5999 / 5999

GCD(7, 857) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 658

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

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

GCD(1, 658) = 658 / 658

GCD(1, 658) = 1

GCD of 903, 637, 857, 658 is 1
