Given Input Data is 287, 378, 581, 906

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

Prime Factorization of 581 is 7 x 83

Prime Factorization of 906 is 2 x 3 x 151

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(287, 378) = 15498

GCD(287, 378) = ( 287 x 378 ) / 15498

GCD(287, 378) = 108486 / 15498

GCD(287, 378) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 581

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

LCM(7, 581) = 581

GCD(7, 581) = ( 7 x 581 ) / 581

GCD(7, 581) = 4067 / 581

GCD(7, 581) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 906

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

LCM(7, 906) = 6342

GCD(7, 906) = ( 7 x 906 ) / 6342

GCD(7, 906) = 6342 / 6342

GCD(7, 906) = 1

GCD of 287, 378, 581, 906 is 1
