Greatest Common Divisior
We found the divisors of 643, 901, 166, 581 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 901, 166, 581 is 1.
Therefore, GCD of numbers 643, 901, 166, 581 is 1
Given Input Data is 643, 901, 166, 581
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 901 is 17 x 53
Prime Factorization of 166 is 2 x 83
Prime Factorization of 581 is 7 x 83
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, 901) = 579343
GCD(643, 901) = ( 643 x 901 ) / 579343
GCD(643, 901) = 579343 / 579343
GCD(643, 901) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 166
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
GCD(1, 166) = 166 / 166
GCD(1, 166) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 581
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
GCD(1, 581) = 581 / 581
GCD(1, 581) = 1
GCD of 643, 901, 166, 581 is 1
