Therefore, GCD of numbers 355, 795, 65, 388 is 1

Given Input Data is 355, 795, 65, 388

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 795 is 3 x 5 x 53

Prime Factorization of 65 is 5 x 13

Prime Factorization of 388 is 2 x 2 x 97

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(355, 795) = 56445

GCD(355, 795) = ( 355 x 795 ) / 56445

GCD(355, 795) = 282225 / 56445

GCD(355, 795) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 65

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

LCM(5, 65) = 65

GCD(5, 65) = ( 5 x 65 ) / 65

GCD(5, 65) = 325 / 65

GCD(5, 65) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 388

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

LCM(5, 388) = 1940

GCD(5, 388) = ( 5 x 388 ) / 1940

GCD(5, 388) = 1940 / 1940

GCD(5, 388) = 1

GCD of 355, 795, 65, 388 is 1
