Greatest Common Divisior

We found the divisors of 161, 302, 420, 604 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 161, 302, 420, 604 is 1.

Therefore, GCD of numbers 161, 302, 420, 604 is 1

Given Input Data is 161, 302, 420, 604

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 302 is 2 x 151

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 604 is 2 x 2 x 151

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(161, 302) = 48622

GCD(161, 302) = ( 161 x 302 ) / 48622

GCD(161, 302) = 48622 / 48622

GCD(161, 302) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 420

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

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

GCD(1, 420) = 420 / 420

GCD(1, 420) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 604

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

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

GCD(1, 604) = 604 / 604

GCD(1, 604) = 1

GCD of 161, 302, 420, 604 is 1
