Greatest Common Divisior

We found the divisors of 15, 73, 31, 37 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 15, 73, 31, 37 is 1.

Therefore, GCD of numbers 15, 73, 31, 37 is 1

Given Input Data is 15, 73, 31, 37

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 73 is 73

Prime Factorization of 31 is 31

Prime Factorization of 37 is 37

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(15, 73) = 1095

GCD(15, 73) = ( 15 x 73 ) / 1095

GCD(15, 73) = 1095 / 1095

GCD(15, 73) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 31

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

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

GCD(1, 31) = 31 / 31

GCD(1, 31) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 37

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

LCM(1, 37) = 37

GCD(1, 37) = ( 1 x 37 ) / 37

GCD(1, 37) = 37 / 37

GCD(1, 37) = 1

GCD of 15, 73, 31, 37 is 1
