Therefore, GCD of numbers 280, 615, 444, 873 is 1

Given Input Data is 280, 615, 444, 873

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 873 is 3 x 3 x 97

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(280, 615) = 34440

GCD(280, 615) = ( 280 x 615 ) / 34440

GCD(280, 615) = 172200 / 34440

GCD(280, 615) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 444

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

LCM(5, 444) = 2220

GCD(5, 444) = ( 5 x 444 ) / 2220

GCD(5, 444) = 2220 / 2220

GCD(5, 444) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 873

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

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

GCD(1, 873) = 873 / 873

GCD(1, 873) = 1

GCD of 280, 615, 444, 873 is 1
