Greatest Common Divisior
We found the divisors of 545, 591, 89, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 545, 591, 89, 645 is 1.
Therefore, GCD of numbers 545, 591, 89, 645 is 1
Given Input Data is 545, 591, 89, 645
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 545 is 5 x 109
Prime Factorization of 591 is 3 x 197
Prime Factorization of 89 is 89
Prime Factorization of 645 is 3 x 5 x 43
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(545, 591) = 322095
GCD(545, 591) = ( 545 x 591 ) / 322095
GCD(545, 591) = 322095 / 322095
GCD(545, 591) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 89
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 89) = 89
GCD(1, 89) = ( 1 x 89 ) / 89
GCD(1, 89) = 89 / 89
GCD(1, 89) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 645
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
GCD(1, 645) = 645 / 645
GCD(1, 645) = 1
GCD of 545, 591, 89, 645 is 1
