Therefore, GCD of numbers 991, 561, 533 is 1

Given Input Data is 991, 561, 533

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

Prime Factorization of 991 is 991

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 533 is 13 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(991, 561) = 555951

GCD(991, 561) = ( 991 x 561 ) / 555951

GCD(991, 561) = 555951 / 555951

GCD(991, 561) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 533

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

LCM(1, 533) = 533

GCD(1, 533) = ( 1 x 533 ) / 533

GCD(1, 533) = 533 / 533

GCD(1, 533) = 1

GCD of 991, 561, 533 is 1
