Greatest Common Divisior
We found the divisors of 447, 209, 36, 644 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 447, 209, 36, 644 is 1.
Therefore, GCD of numbers 447, 209, 36, 644 is 1
Given Input Data is 447, 209, 36, 644
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 447 is 3 x 149
Prime Factorization of 209 is 11 x 19
Prime Factorization of 36 is 2 x 2 x 3 x 3
Prime Factorization of 644 is 2 x 2 x 7 x 23
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(447, 209) = 93423
GCD(447, 209) = ( 447 x 209 ) / 93423
GCD(447, 209) = 93423 / 93423
GCD(447, 209) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 36
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 36) = 36
GCD(1, 36) = ( 1 x 36 ) / 36
GCD(1, 36) = 36 / 36
GCD(1, 36) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 644
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
GCD(1, 644) = 644 / 644
GCD(1, 644) = 1
GCD of 447, 209, 36, 644 is 1
