Therefore, GCD of numbers 991, 392, 218 is 1

Given Input Data is 991, 392, 218

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

Prime Factorization of 991 is 991

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 218 is 2 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(991, 392) = 388472

GCD(991, 392) = ( 991 x 392 ) / 388472

GCD(991, 392) = 388472 / 388472

GCD(991, 392) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 218

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

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

GCD(1, 218) = 218 / 218

GCD(1, 218) = 1

GCD of 991, 392, 218 is 1
