Greatest Common Divisior

We found the divisors of 215, 652, 501, 861 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 652, 501, 861 is 1.

Therefore, GCD of numbers 215, 652, 501, 861 is 1

Given Input Data is 215, 652, 501, 861

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 652 is 2 x 2 x 163

Prime Factorization of 501 is 3 x 167

Prime Factorization of 861 is 3 x 7 x 41

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(215, 652) = 140180

GCD(215, 652) = ( 215 x 652 ) / 140180

GCD(215, 652) = 140180 / 140180

GCD(215, 652) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 501

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

LCM(1, 501) = 501

GCD(1, 501) = ( 1 x 501 ) / 501

GCD(1, 501) = 501 / 501

GCD(1, 501) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 215, 652, 501, 861 is 1
