Therefore, GCD of numbers 129, 903, 713, 781 is 1

Given Input Data is 129, 903, 713, 781

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 713 is 23 x 31

Prime Factorization of 781 is 11 x 71

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(129, 903) = 903

GCD(129, 903) = ( 129 x 903 ) / 903

GCD(129, 903) = 116487 / 903

GCD(129, 903) = 129

Step2:

Here we consider the GCD from the above i.e. 129 as first number and the next as 713

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

LCM(129, 713) = 91977

GCD(129, 713) = ( 129 x 713 ) / 91977

GCD(129, 713) = 91977 / 91977

GCD(129, 713) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 781

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

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

GCD(1, 781) = 781 / 781

GCD(1, 781) = 1

GCD of 129, 903, 713, 781 is 1
