Therefore, GCD of numbers 144, 491, 81, 246 is 1

Given Input Data is 144, 491, 81, 246

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

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 491 is 491

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 246 is 2 x 3 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(144, 491) = 70704

GCD(144, 491) = ( 144 x 491 ) / 70704

GCD(144, 491) = 70704 / 70704

GCD(144, 491) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 246

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

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

GCD(1, 246) = 246 / 246

GCD(1, 246) = 1

GCD of 144, 491, 81, 246 is 1
