We found the divisors of 991, 254, 405 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 991, 254, 405 is 1.

Therefore, GCD of numbers 991, 254, 405 is 1

Given Input Data is 991, 254, 405

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

Prime Factorization of 991 is 991

Prime Factorization of 254 is 2 x 127

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

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, 254) = 251714

GCD(991, 254) = ( 991 x 254 ) / 251714

GCD(991, 254) = 251714 / 251714

GCD(991, 254) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 405

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

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

GCD(1, 405) = 405 / 405

GCD(1, 405) = 1

GCD of 991, 254, 405 is 1
