Greatest Common Divisior
We found the divisors of 989, 204, 19, 637 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 989, 204, 19, 637 is 1.
Therefore, GCD of numbers 989, 204, 19, 637 is 1
Given Input Data is 989, 204, 19, 637
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 989 is 23 x 43
Prime Factorization of 204 is 2 x 2 x 3 x 17
Prime Factorization of 19 is 19
Prime Factorization of 637 is 7 x 7 x 13
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(989, 204) = 201756
GCD(989, 204) = ( 989 x 204 ) / 201756
GCD(989, 204) = 201756 / 201756
GCD(989, 204) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 19
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
GCD(1, 19) = 19 / 19
GCD(1, 19) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 637
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
GCD(1, 637) = 637 / 637
GCD(1, 637) = 1
GCD of 989, 204, 19, 637 is 1
