We found the divisors of 28, 68, 37 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 28, 68, 37 is 1.

Therefore, GCD of numbers 28, 68, 37 is 1

Given Input Data is 28, 68, 37

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 68 is 2 x 2 x 17

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(28, 68) = 476

GCD(28, 68) = ( 28 x 68 ) / 476

GCD(28, 68) = 1904 / 476

GCD(28, 68) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 37

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

LCM(4, 37) = 148

GCD(4, 37) = ( 4 x 37 ) / 148

GCD(4, 37) = 148 / 148

GCD(4, 37) = 1

GCD of 28, 68, 37 is 1
