Therefore, GCD of numbers 963, 903, 763, 553 is 1

Given Input Data is 963, 903, 763, 553

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

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 763 is 7 x 109

Prime Factorization of 553 is 7 x 79

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(963, 903) = 289863

GCD(963, 903) = ( 963 x 903 ) / 289863

GCD(963, 903) = 869589 / 289863

GCD(963, 903) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 763

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

LCM(3, 763) = 2289

GCD(3, 763) = ( 3 x 763 ) / 2289

GCD(3, 763) = 2289 / 2289

GCD(3, 763) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 553

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

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

GCD(1, 553) = 553 / 553

GCD(1, 553) = 1

GCD of 963, 903, 763, 553 is 1
