Greatest Common Divisior
We found the divisors of 645, 418, 662, 936 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 418, 662, 936 is 1.
Therefore, GCD of numbers 645, 418, 662, 936 is 1
Given Input Data is 645, 418, 662, 936
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 418 is 2 x 11 x 19
Prime Factorization of 662 is 2 x 331
Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13
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(645, 418) = 269610
GCD(645, 418) = ( 645 x 418 ) / 269610
GCD(645, 418) = 269610 / 269610
GCD(645, 418) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 662
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
GCD(1, 662) = 662 / 662
GCD(1, 662) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 936
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 936) = 936
GCD(1, 936) = ( 1 x 936 ) / 936
GCD(1, 936) = 936 / 936
GCD(1, 936) = 1
GCD of 645, 418, 662, 936 is 1
