We found the divisors of 206, 214, 45, 456 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 206, 214, 45, 456 is 1.

Therefore, GCD of numbers 206, 214, 45, 456 is 1

Given Input Data is 206, 214, 45, 456

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

Prime Factorization of 206 is 2 x 103

Prime Factorization of 214 is 2 x 107

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

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(206, 214) = 22042

GCD(206, 214) = ( 206 x 214 ) / 22042

GCD(206, 214) = 44084 / 22042

GCD(206, 214) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 45

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

LCM(2, 45) = 90

GCD(2, 45) = ( 2 x 45 ) / 90

GCD(2, 45) = 90 / 90

GCD(2, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 456

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

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

GCD(1, 456) = 456 / 456

GCD(1, 456) = 1

GCD of 206, 214, 45, 456 is 1
