Therefore, GCD of numbers 580, 995, 18, 943 is 1

Given Input Data is 580, 995, 18, 943

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

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

Prime Factorization of 995 is 5 x 199

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 943 is 23 x 41

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(580, 995) = 115420

GCD(580, 995) = ( 580 x 995 ) / 115420

GCD(580, 995) = 577100 / 115420

GCD(580, 995) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 18

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

LCM(5, 18) = 90

GCD(5, 18) = ( 5 x 18 ) / 90

GCD(5, 18) = 90 / 90

GCD(5, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 943

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

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

GCD(1, 943) = 943 / 943

GCD(1, 943) = 1

GCD of 580, 995, 18, 943 is 1
