Greatest Common Divisior
We found the divisors of 991, 426, 261, 443 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 991, 426, 261, 443 is 1.
Therefore, GCD of numbers 991, 426, 261, 443 is 1
Given Input Data is 991, 426, 261, 443
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 991 is 991
Prime Factorization of 426 is 2 x 3 x 71
Prime Factorization of 261 is 3 x 3 x 29
Prime Factorization of 443 is 443
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(991, 426) = 422166
GCD(991, 426) = ( 991 x 426 ) / 422166
GCD(991, 426) = 422166 / 422166
GCD(991, 426) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 261
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
GCD(1, 261) = 261 / 261
GCD(1, 261) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 443
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
GCD(1, 443) = 443 / 443
GCD(1, 443) = 1
GCD of 991, 426, 261, 443 is 1
