Therefore, GCD of numbers 406, 959, 87, 812 is 1

Given Input Data is 406, 959, 87, 812

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

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 959 is 7 x 137

Prime Factorization of 87 is 3 x 29

Prime Factorization of 812 is 2 x 2 x 7 x 29

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(406, 959) = 55622

GCD(406, 959) = ( 406 x 959 ) / 55622

GCD(406, 959) = 389354 / 55622

GCD(406, 959) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 87

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

LCM(7, 87) = 609

GCD(7, 87) = ( 7 x 87 ) / 609

GCD(7, 87) = 609 / 609

GCD(7, 87) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 812

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

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

GCD(1, 812) = 812 / 812

GCD(1, 812) = 1

GCD of 406, 959, 87, 812 is 1
