Therefore, GCD of numbers 475, 520, 87, 812 is 1

Given Input Data is 475, 520, 87, 812

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

Prime Factorization of 475 is 5 x 5 x 19

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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(475, 520) = 49400

GCD(475, 520) = ( 475 x 520 ) / 49400

GCD(475, 520) = 247000 / 49400

GCD(475, 520) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 87

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

LCM(5, 87) = 435

GCD(5, 87) = ( 5 x 87 ) / 435

GCD(5, 87) = 435 / 435

GCD(5, 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 475, 520, 87, 812 is 1
