1, 2, 109, 218
Greatest Common Divisior
We found the divisors of 646, 923, 53, 218 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 646, 923, 53, 218 is 1.
Therefore, GCD of numbers 646, 923, 53, 218 is 1
Given Input Data is 646, 923, 53, 218
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 923 is 13 x 71
Prime Factorization of 53 is 53
Prime Factorization of 218 is 2 x 109
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(646, 923) = 596258
GCD(646, 923) = ( 646 x 923 ) / 596258
GCD(646, 923) = 596258 / 596258
GCD(646, 923) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 53
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 53) = 53
GCD(1, 53) = ( 1 x 53 ) / 53
GCD(1, 53) = 53 / 53
GCD(1, 53) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 218
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
GCD(1, 218) = 218 / 218
GCD(1, 218) = 1
GCD of 646, 923, 53, 218 is 1
