Therefore, GCD of numbers 180, 485, 981 is 1

Given Input Data is 180, 485, 981

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

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 485 is 5 x 97

Prime Factorization of 981 is 3 x 3 x 109

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(180, 485) = 17460

GCD(180, 485) = ( 180 x 485 ) / 17460

GCD(180, 485) = 87300 / 17460

GCD(180, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 981

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

LCM(5, 981) = 4905

GCD(5, 981) = ( 5 x 981 ) / 4905

GCD(5, 981) = 4905 / 4905

GCD(5, 981) = 1

GCD of 180, 485, 981 is 1
