Given Input Data is 751, 428, 81, 835

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

Prime Factorization of 751 is 751

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 835 is 5 x 167

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(751, 428) = 321428

GCD(751, 428) = ( 751 x 428 ) / 321428

GCD(751, 428) = 321428 / 321428

GCD(751, 428) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 835

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

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

GCD(1, 835) = 835 / 835

GCD(1, 835) = 1

GCD of 751, 428, 81, 835 is 1
