Greatest Common Divisior

We found the divisors of 54, 2, 15, 73 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 54, 2, 15, 73 is 1.

Therefore, GCD of numbers 54, 2, 15, 73 is 1

Given Input Data is 54, 2, 15, 73

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 2 is 2

Prime Factorization of 15 is 3 x 5

Prime Factorization of 73 is 73

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(54, 2) = 54

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

GCD(54, 2) = 108 / 54

GCD(54, 2) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 15

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

LCM(2, 15) = 30

GCD(2, 15) = ( 2 x 15 ) / 30

GCD(2, 15) = 30 / 30

GCD(2, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 73

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

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

GCD(1, 73) = 73 / 73

GCD(1, 73) = 1

GCD of 54, 2, 15, 73 is 1
