We found the divisors of 75, 47, 81, 97 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 75, 47, 81, 97 is 1.

Therefore, GCD of numbers 75, 47, 81, 97 is 1

Given Input Data is 75, 47, 81, 97

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 47 is 47

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

Prime Factorization of 97 is 97

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(75, 47) = 3525

GCD(75, 47) = ( 75 x 47 ) / 3525

GCD(75, 47) = 3525 / 3525

GCD(75, 47) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 97

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

LCM(1, 97) = 97

GCD(1, 97) = ( 1 x 97 ) / 97

GCD(1, 97) = 97 / 97

GCD(1, 97) = 1

GCD of 75, 47, 81, 97 is 1
