Therefore, GCD of numbers 297, 647, 811, 483 is 1

Given Input Data is 297, 647, 811, 483

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

Prime Factorization of 297 is 3 x 3 x 3 x 11

Prime Factorization of 647 is 647

Prime Factorization of 811 is 811

Prime Factorization of 483 is 3 x 7 x 23

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(297, 647) = 192159

GCD(297, 647) = ( 297 x 647 ) / 192159

GCD(297, 647) = 192159 / 192159

GCD(297, 647) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 483

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

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

GCD(1, 483) = 483 / 483

GCD(1, 483) = 1

GCD of 297, 647, 811, 483 is 1
