So the Greatest Common Divisior 27, 88, 42, 75 is 1.

Therefore, GCD of numbers 27, 88, 42, 75 is 1

Given Input Data is 27, 88, 42, 75

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

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 42 is 2 x 3 x 7

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(27, 88) = 2376

GCD(27, 88) = ( 27 x 88 ) / 2376

GCD(27, 88) = 2376 / 2376

GCD(27, 88) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 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 27, 88, 42, 75 is 1
