Greatest Common Divisior

We found the divisors of 83, 455, 721, 610 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 83, 455, 721, 610 is 1.

Therefore, GCD of numbers 83, 455, 721, 610 is 1

Given Input Data is 83, 455, 721, 610

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

Prime Factorization of 83 is 83

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 721 is 7 x 103

Prime Factorization of 610 is 2 x 5 x 61

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(83, 455) = 37765

GCD(83, 455) = ( 83 x 455 ) / 37765

GCD(83, 455) = 37765 / 37765

GCD(83, 455) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 721

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

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

GCD(1, 721) = 721 / 721

GCD(1, 721) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 610

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

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

GCD(1, 610) = 610 / 610

GCD(1, 610) = 1

GCD of 83, 455, 721, 610 is 1
