Given Input Data is 172, 916, 547, 878

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 916 is 2 x 2 x 229

Prime Factorization of 547 is 547

Prime Factorization of 878 is 2 x 439

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(172, 916) = 39388

GCD(172, 916) = ( 172 x 916 ) / 39388

GCD(172, 916) = 157552 / 39388

GCD(172, 916) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 547

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

LCM(4, 547) = 2188

GCD(4, 547) = ( 4 x 547 ) / 2188

GCD(4, 547) = 2188 / 2188

GCD(4, 547) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 878

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

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

GCD(1, 878) = 878 / 878

GCD(1, 878) = 1

GCD of 172, 916, 547, 878 is 1
