Greatest Common Divisior
We found the divisors of 287, 143, 947, 638 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 287, 143, 947, 638 is 1.
Therefore, GCD of numbers 287, 143, 947, 638 is 1
Given Input Data is 287, 143, 947, 638
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 287 is 7 x 41
Prime Factorization of 143 is 11 x 13
Prime Factorization of 947 is 947
Prime Factorization of 638 is 2 x 11 x 29
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(287, 143) = 41041
GCD(287, 143) = ( 287 x 143 ) / 41041
GCD(287, 143) = 41041 / 41041
GCD(287, 143) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 947
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
GCD(1, 947) = 947 / 947
GCD(1, 947) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 638
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
GCD(1, 638) = 638 / 638
GCD(1, 638) = 1
GCD of 287, 143, 947, 638 is 1
