Therefore, GCD of numbers 87, 615, 818, 392 is 1

Given Input Data is 87, 615, 818, 392

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 818 is 2 x 409

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

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(87, 615) = 17835

GCD(87, 615) = ( 87 x 615 ) / 17835

GCD(87, 615) = 53505 / 17835

GCD(87, 615) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 818

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

LCM(3, 818) = 2454

GCD(3, 818) = ( 3 x 818 ) / 2454

GCD(3, 818) = 2454 / 2454

GCD(3, 818) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 392

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

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

GCD(1, 392) = 392 / 392

GCD(1, 392) = 1

GCD of 87, 615, 818, 392 is 1
