We found the divisors of 71, 81, 93, 75 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 81, 93, 75 is 1.

Therefore, GCD of numbers 71, 81, 93, 75 is 1

Given Input Data is 71, 81, 93, 75

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

Prime Factorization of 71 is 71

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

Prime Factorization of 93 is 3 x 31

Prime Factorization of 75 is 3 x 5 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(71, 81) = 5751

GCD(71, 81) = ( 71 x 81 ) / 5751

GCD(71, 81) = 5751 / 5751

GCD(71, 81) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 93

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

LCM(1, 93) = 93

GCD(1, 93) = ( 1 x 93 ) / 93

GCD(1, 93) = 93 / 93

GCD(1, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

GCD of 71, 81, 93, 75 is 1
