Therefore, GCD of numbers 991, 513, 473 is 1

Given Input Data is 991, 513, 473

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

Prime Factorization of 991 is 991

Prime Factorization of 513 is 3 x 3 x 3 x 19

Prime Factorization of 473 is 11 x 43

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, 513) = 508383

GCD(991, 513) = ( 991 x 513 ) / 508383

GCD(991, 513) = 508383 / 508383

GCD(991, 513) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 473

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

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

GCD(1, 473) = 473 / 473

GCD(1, 473) = 1

GCD of 991, 513, 473 is 1
