Therefore, GCD of numbers 621, 438, 166, 331 is 1

Given Input Data is 621, 438, 166, 331

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

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 166 is 2 x 83

Prime Factorization of 331 is 331

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(621, 438) = 90666

GCD(621, 438) = ( 621 x 438 ) / 90666

GCD(621, 438) = 271998 / 90666

GCD(621, 438) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 166

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

LCM(3, 166) = 498

GCD(3, 166) = ( 3 x 166 ) / 498

GCD(3, 166) = 498 / 498

GCD(3, 166) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 331

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

LCM(1, 331) = 331

GCD(1, 331) = ( 1 x 331 ) / 331

GCD(1, 331) = 331 / 331

GCD(1, 331) = 1

GCD of 621, 438, 166, 331 is 1
