We found the divisors of 257, 199, 611, 210 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 257, 199, 611, 210 is 1.

Therefore, GCD of numbers 257, 199, 611, 210 is 1

Given Input Data is 257, 199, 611, 210

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

Prime Factorization of 257 is 257

Prime Factorization of 199 is 199

Prime Factorization of 611 is 13 x 47

Prime Factorization of 210 is 2 x 3 x 5 x 7

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(257, 199) = 51143

GCD(257, 199) = ( 257 x 199 ) / 51143

GCD(257, 199) = 51143 / 51143

GCD(257, 199) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 611

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

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

GCD(1, 611) = 611 / 611

GCD(1, 611) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

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

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 257, 199, 611, 210 is 1
