Therefore, GCD of numbers 81, 408, 737, 928 is 1

Given Input Data is 81, 408, 737, 928

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 408 is 2 x 2 x 2 x 3 x 17

Prime Factorization of 737 is 11 x 67

Prime Factorization of 928 is 2 x 2 x 2 x 2 x 2 x 29

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, 408) = 11016

GCD(81, 408) = ( 81 x 408 ) / 11016

GCD(81, 408) = 33048 / 11016

GCD(81, 408) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 737

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

LCM(3, 737) = 2211

GCD(3, 737) = ( 3 x 737 ) / 2211

GCD(3, 737) = 2211 / 2211

GCD(3, 737) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 928

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

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

GCD(1, 928) = 928 / 928

GCD(1, 928) = 1

GCD of 81, 408, 737, 928 is 1
