Given Input Data is 812, 666, 877, 870

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

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

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 877 is 877

Prime Factorization of 870 is 2 x 3 x 5 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(812, 666) = 270396

GCD(812, 666) = ( 812 x 666 ) / 270396

GCD(812, 666) = 540792 / 270396

GCD(812, 666) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 877

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

LCM(2, 877) = 1754

GCD(2, 877) = ( 2 x 877 ) / 1754

GCD(2, 877) = 1754 / 1754

GCD(2, 877) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 870

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

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

GCD(1, 870) = 870 / 870

GCD(1, 870) = 1

GCD of 812, 666, 877, 870 is 1
