Therefore, GCD of numbers 163, 227, 79, 620 is 1

Given Input Data is 163, 227, 79, 620

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

Prime Factorization of 163 is 163

Prime Factorization of 227 is 227

Prime Factorization of 79 is 79

Prime Factorization of 620 is 2 x 2 x 5 x 31

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(163, 227) = 37001

GCD(163, 227) = ( 163 x 227 ) / 37001

GCD(163, 227) = 37001 / 37001

GCD(163, 227) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

GCD of 163, 227, 79, 620 is 1
