So the Greatest Common Divisior 27, 44, 81, 63 is 1.

Therefore, GCD of numbers 27, 44, 81, 63 is 1

Given Input Data is 27, 44, 81, 63

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 44 is 2 x 2 x 11

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

Prime Factorization of 63 is 3 x 3 x 7

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, 44) = 1188

GCD(27, 44) = ( 27 x 44 ) / 1188

GCD(27, 44) = 1188 / 1188

GCD(27, 44) = 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 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

GCD of 27, 44, 81, 63 is 1
