We found the divisors of 406, 451, 785, 230 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 406, 451, 785, 230 is 1.

Therefore, GCD of numbers 406, 451, 785, 230 is 1

Given Input Data is 406, 451, 785, 230

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

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 451 is 11 x 41

Prime Factorization of 785 is 5 x 157

Prime Factorization of 230 is 2 x 5 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(406, 451) = 183106

GCD(406, 451) = ( 406 x 451 ) / 183106

GCD(406, 451) = 183106 / 183106

GCD(406, 451) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 785

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

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

GCD(1, 785) = 785 / 785

GCD(1, 785) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 230

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

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

GCD(1, 230) = 230 / 230

GCD(1, 230) = 1

GCD of 406, 451, 785, 230 is 1
