Greatest Common Divisior

We found the divisors of 170, 347, 213, 180 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 170, 347, 213, 180 is 1.

Therefore, GCD of numbers 170, 347, 213, 180 is 1

Given Input Data is 170, 347, 213, 180

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

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 347 is 347

Prime Factorization of 213 is 3 x 71

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

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(170, 347) = 58990

GCD(170, 347) = ( 170 x 347 ) / 58990

GCD(170, 347) = 58990 / 58990

GCD(170, 347) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 213

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

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

GCD(1, 213) = 213 / 213

GCD(1, 213) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 180

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

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

GCD(1, 180) = 180 / 180

GCD(1, 180) = 1

GCD of 170, 347, 213, 180 is 1
