Therefore, GCD of numbers 234, 531, 620 is 1

Given Input Data is 234, 531, 620

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

Prime Factorization of 234 is 2 x 3 x 3 x 13

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 620 is 2 x 2 x 5 x 31

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(234, 531) = 13806

GCD(234, 531) = ( 234 x 531 ) / 13806

GCD(234, 531) = 124254 / 13806

GCD(234, 531) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 620

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

LCM(9, 620) = 5580

GCD(9, 620) = ( 9 x 620 ) / 5580

GCD(9, 620) = 5580 / 5580

GCD(9, 620) = 1

GCD of 234, 531, 620 is 1
