Greatest Common Divisior

We found the divisors of 213, 361, 70, 682 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 213, 361, 70, 682 is 1.

Therefore, GCD of numbers 213, 361, 70, 682 is 1

Given Input Data is 213, 361, 70, 682

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

Prime Factorization of 213 is 3 x 71

Prime Factorization of 361 is 19 x 19

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 682 is 2 x 11 x 31

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(213, 361) = 76893

GCD(213, 361) = ( 213 x 361 ) / 76893

GCD(213, 361) = 76893 / 76893

GCD(213, 361) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 682

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

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

GCD(1, 682) = 682 / 682

GCD(1, 682) = 1

GCD of 213, 361, 70, 682 is 1
