Therefore, GCD of numbers 618, 417, 821, 443 is 1

Given Input Data is 618, 417, 821, 443

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 417 is 3 x 139

Prime Factorization of 821 is 821

Prime Factorization of 443 is 443

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(618, 417) = 85902

GCD(618, 417) = ( 618 x 417 ) / 85902

GCD(618, 417) = 257706 / 85902

GCD(618, 417) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 821

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

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

GCD(3, 821) = 2463 / 2463

GCD(3, 821) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 443

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

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

GCD(1, 443) = 443 / 443

GCD(1, 443) = 1

GCD of 618, 417, 821, 443 is 1
