We found the divisors of 397, 700, 120 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 397, 700, 120 is 1.

Therefore, GCD of numbers 397, 700, 120 is 1

Given Input Data is 397, 700, 120

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

Prime Factorization of 397 is 397

Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7

Prime Factorization of 120 is 2 x 2 x 2 x 3 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(397, 700) = 277900

GCD(397, 700) = ( 397 x 700 ) / 277900

GCD(397, 700) = 277900 / 277900

GCD(397, 700) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 120

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

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

GCD(1, 120) = 120 / 120

GCD(1, 120) = 1

GCD of 397, 700, 120 is 1
