We found the divisors of 72, 18, 37 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 72, 18, 37 is 1.

Therefore, GCD of numbers 72, 18, 37 is 1

Given Input Data is 72, 18, 37

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

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 18 is 2 x 3 x 3

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(72, 18) = 72

GCD(72, 18) = ( 72 x 18 ) / 72

GCD(72, 18) = 1296 / 72

GCD(72, 18) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 37

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

LCM(18, 37) = 666

GCD(18, 37) = ( 18 x 37 ) / 666

GCD(18, 37) = 666 / 666

GCD(18, 37) = 1

GCD of 72, 18, 37 is 1
