Therefore, GCD of numbers 793, 904, 72, 220 is 1

Given Input Data is 793, 904, 72, 220

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

Prime Factorization of 793 is 13 x 61

Prime Factorization of 904 is 2 x 2 x 2 x 113

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 220 is 2 x 2 x 5 x 11

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(793, 904) = 716872

GCD(793, 904) = ( 793 x 904 ) / 716872

GCD(793, 904) = 716872 / 716872

GCD(793, 904) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

GCD of 793, 904, 72, 220 is 1
