Greatest Common Divisior
We found the divisors of 643, 133, 885, 417 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 133, 885, 417 is 1.
Therefore, GCD of numbers 643, 133, 885, 417 is 1
Given Input Data is 643, 133, 885, 417
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 133 is 7 x 19
Prime Factorization of 885 is 3 x 5 x 59
Prime Factorization of 417 is 3 x 139
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(643, 133) = 85519
GCD(643, 133) = ( 643 x 133 ) / 85519
GCD(643, 133) = 85519 / 85519
GCD(643, 133) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 885
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
GCD(1, 885) = 885 / 885
GCD(1, 885) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 417
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
GCD(1, 417) = 417 / 417
GCD(1, 417) = 1
GCD of 643, 133, 885, 417 is 1
