Therefore, GCD of numbers 818, 383, 580, 689 is 1

Given Input Data is 818, 383, 580, 689

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

Prime Factorization of 818 is 2 x 409

Prime Factorization of 383 is 383

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 689 is 13 x 53

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(818, 383) = 313294

GCD(818, 383) = ( 818 x 383 ) / 313294

GCD(818, 383) = 313294 / 313294

GCD(818, 383) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 580

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

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

GCD(1, 580) = 580 / 580

GCD(1, 580) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 689

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

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

GCD(1, 689) = 689 / 689

GCD(1, 689) = 1

GCD of 818, 383, 580, 689 is 1
