Greatest Common Divisior
We found the divisors of 642, 116, 481, 865 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 642, 116, 481, 865 is 1.
Therefore, GCD of numbers 642, 116, 481, 865 is 1
Given Input Data is 642, 116, 481, 865
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 642 is 2 x 3 x 107
Prime Factorization of 116 is 2 x 2 x 29
Prime Factorization of 481 is 13 x 37
Prime Factorization of 865 is 5 x 173
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(642, 116) = 37236
GCD(642, 116) = ( 642 x 116 ) / 37236
GCD(642, 116) = 74472 / 37236
GCD(642, 116) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 481
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 481) = 962
GCD(2, 481) = ( 2 x 481 ) / 962
GCD(2, 481) = 962 / 962
GCD(2, 481) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 865
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
GCD(1, 865) = 865 / 865
GCD(1, 865) = 1
GCD of 642, 116, 481, 865 is 1
