Greatest Common Divisior

We found the divisors of 715, 636, 43, 401 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 715, 636, 43, 401 is 1.

Therefore, GCD of numbers 715, 636, 43, 401 is 1

Given Input Data is 715, 636, 43, 401

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 43 is 43

Prime Factorization of 401 is 401

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(715, 636) = 454740

GCD(715, 636) = ( 715 x 636 ) / 454740

GCD(715, 636) = 454740 / 454740

GCD(715, 636) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

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

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 401

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

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

GCD(1, 401) = 401 / 401

GCD(1, 401) = 1

GCD of 715, 636, 43, 401 is 1
