We found the divisors of 730, 373, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 730, 373, 20 is 1.

Therefore, GCD of numbers 730, 373, 20 is 1

Given Input Data is 730, 373, 20

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

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 373 is 373

Prime Factorization of 20 is 2 x 2 x 5

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(730, 373) = 272290

GCD(730, 373) = ( 730 x 373 ) / 272290

GCD(730, 373) = 272290 / 272290

GCD(730, 373) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 730, 373, 20 is 1
