1, 919
Greatest Common Divisior
We found the divisors of 817, 643, 676, 919 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 817, 643, 676, 919 is 1.
Therefore, GCD of numbers 817, 643, 676, 919 is 1
Given Input Data is 817, 643, 676, 919
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 817 is 19 x 43
Prime Factorization of 643 is 643
Prime Factorization of 676 is 2 x 2 x 13 x 13
Prime Factorization of 919 is 919
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(817, 643) = 525331
GCD(817, 643) = ( 817 x 643 ) / 525331
GCD(817, 643) = 525331 / 525331
GCD(817, 643) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 676
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
GCD(1, 676) = 676 / 676
GCD(1, 676) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 919
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
GCD(1, 919) = 919 / 919
GCD(1, 919) = 1
GCD of 817, 643, 676, 919 is 1
