Given Input Data is 511, 728, 263, 441

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 263 is 263

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(511, 728) = 53144

GCD(511, 728) = ( 511 x 728 ) / 53144

GCD(511, 728) = 372008 / 53144

GCD(511, 728) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 263

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

LCM(7, 263) = 1841

GCD(7, 263) = ( 7 x 263 ) / 1841

GCD(7, 263) = 1841 / 1841

GCD(7, 263) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 511, 728, 263, 441 is 1
