Therefore, GCD of numbers 81, 555, 752, 405 is 1

Given Input Data is 81, 555, 752, 405

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 752 is 2 x 2 x 2 x 2 x 47

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(81, 555) = 14985

GCD(81, 555) = ( 81 x 555 ) / 14985

GCD(81, 555) = 44955 / 14985

GCD(81, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 752

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

LCM(3, 752) = 2256

GCD(3, 752) = ( 3 x 752 ) / 2256

GCD(3, 752) = 2256 / 2256

GCD(3, 752) = 1

Step3:

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 81, 555, 752, 405 is 1
