Greatest Common Divisior

We found the divisors of 30, 32, 27, 63 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 32, 27, 63 is 1.

Therefore, GCD of numbers 30, 32, 27, 63 is 1

Given Input Data is 30, 32, 27, 63

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 27 is 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(30, 32) = 480

GCD(30, 32) = ( 30 x 32 ) / 480

GCD(30, 32) = 960 / 480

GCD(30, 32) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 27

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

LCM(2, 27) = 54

GCD(2, 27) = ( 2 x 27 ) / 54

GCD(2, 27) = 54 / 54

GCD(2, 27) = 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 30, 32, 27, 63 is 1
