Given Input Data is 172, 856, 452

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 856 is 2 x 2 x 2 x 107

Prime Factorization of 452 is 2 x 2 x 113

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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, 856) = 36808

GCD(172, 856) = ( 172 x 856 ) / 36808

GCD(172, 856) = 147232 / 36808

GCD(172, 856) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 452

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

LCM(4, 452) = 452

GCD(4, 452) = ( 4 x 452 ) / 452

GCD(4, 452) = 1808 / 452

GCD(4, 452) = 4

GCD of 172, 856, 452 is 4
