Given Input Data is 393, 936, 793, 436

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

Prime Factorization of 393 is 3 x 131

Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13

Prime Factorization of 793 is 13 x 61

Prime Factorization of 436 is 2 x 2 x 109

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(393, 936) = 122616

GCD(393, 936) = ( 393 x 936 ) / 122616

GCD(393, 936) = 367848 / 122616

GCD(393, 936) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 793

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

LCM(3, 793) = 2379

GCD(3, 793) = ( 3 x 793 ) / 2379

GCD(3, 793) = 2379 / 2379

GCD(3, 793) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 436

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

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

GCD(1, 436) = 436 / 436

GCD(1, 436) = 1

GCD of 393, 936, 793, 436 is 1
