Therefore, GCD of numbers 198, 801, 641 is 1

Given Input Data is 198, 801, 641

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

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 801 is 3 x 3 x 89

Prime Factorization of 641 is 641

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(198, 801) = 17622

GCD(198, 801) = ( 198 x 801 ) / 17622

GCD(198, 801) = 158598 / 17622

GCD(198, 801) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 641

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

LCM(9, 641) = 5769

GCD(9, 641) = ( 9 x 641 ) / 5769

GCD(9, 641) = 5769 / 5769

GCD(9, 641) = 1

GCD of 198, 801, 641 is 1
