We found the divisors of 394, 395, 45, 207 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 394, 395, 45, 207 is 1.

Therefore, GCD of numbers 394, 395, 45, 207 is 1

Given Input Data is 394, 395, 45, 207

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

Prime Factorization of 394 is 2 x 197

Prime Factorization of 395 is 5 x 79

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 207 is 3 x 3 x 23

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(394, 395) = 155630

GCD(394, 395) = ( 394 x 395 ) / 155630

GCD(394, 395) = 155630 / 155630

GCD(394, 395) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 45

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

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

GCD(1, 45) = 45 / 45

GCD(1, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 207

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

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

GCD(1, 207) = 207 / 207

GCD(1, 207) = 1

GCD of 394, 395, 45, 207 is 1
