We found the divisors of 61, 210, 547, 309 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 210, 547, 309 is 1.

Therefore, GCD of numbers 61, 210, 547, 309 is 1

Given Input Data is 61, 210, 547, 309

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

Prime Factorization of 61 is 61

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

Prime Factorization of 547 is 547

Prime Factorization of 309 is 3 x 103

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(61, 210) = 12810

GCD(61, 210) = ( 61 x 210 ) / 12810

GCD(61, 210) = 12810 / 12810

GCD(61, 210) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 547

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

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

GCD(1, 547) = 547 / 547

GCD(1, 547) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 309

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

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

GCD(1, 309) = 309 / 309

GCD(1, 309) = 1

GCD of 61, 210, 547, 309 is 1
