Given Input Data is 291, 720, 362, 823

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

Prime Factorization of 291 is 3 x 97

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 362 is 2 x 181

Prime Factorization of 823 is 823

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(291, 720) = 69840

GCD(291, 720) = ( 291 x 720 ) / 69840

GCD(291, 720) = 209520 / 69840

GCD(291, 720) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 362

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

LCM(3, 362) = 1086

GCD(3, 362) = ( 3 x 362 ) / 1086

GCD(3, 362) = 1086 / 1086

GCD(3, 362) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 823

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

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

GCD(1, 823) = 823 / 823

GCD(1, 823) = 1

GCD of 291, 720, 362, 823 is 1
