Therefore, GCD of numbers 471, 219, 79, 628 is 1

Given Input Data is 471, 219, 79, 628

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

Prime Factorization of 471 is 3 x 157

Prime Factorization of 219 is 3 x 73

Prime Factorization of 79 is 79

Prime Factorization of 628 is 2 x 2 x 157

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(471, 219) = 34383

GCD(471, 219) = ( 471 x 219 ) / 34383

GCD(471, 219) = 103149 / 34383

GCD(471, 219) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 79

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

LCM(3, 79) = 237

GCD(3, 79) = ( 3 x 79 ) / 237

GCD(3, 79) = 237 / 237

GCD(3, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 628

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

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

GCD(1, 628) = 628 / 628

GCD(1, 628) = 1

GCD of 471, 219, 79, 628 is 1
