Therefore, GCD of numbers 912, 420, 163, 730 is 1

Given Input Data is 912, 420, 163, 730

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

Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 163 is 163

Prime Factorization of 730 is 2 x 5 x 73

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(912, 420) = 31920

GCD(912, 420) = ( 912 x 420 ) / 31920

GCD(912, 420) = 383040 / 31920

GCD(912, 420) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 163

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

LCM(12, 163) = 1956

GCD(12, 163) = ( 12 x 163 ) / 1956

GCD(12, 163) = 1956 / 1956

GCD(12, 163) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 730

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

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

GCD(1, 730) = 730 / 730

GCD(1, 730) = 1

GCD of 912, 420, 163, 730 is 1
