Greatest Common Divisior
We found the divisors of 927, 387, 646, 245 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 927, 387, 646, 245 is 1.
Therefore, GCD of numbers 927, 387, 646, 245 is 1
Given Input Data is 927, 387, 646, 245
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 927 is 3 x 3 x 103
Prime Factorization of 387 is 3 x 3 x 43
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 245 is 5 x 7 x 7
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(927, 387) = 39861
GCD(927, 387) = ( 927 x 387 ) / 39861
GCD(927, 387) = 358749 / 39861
GCD(927, 387) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 646) = 5814
GCD(9, 646) = ( 9 x 646 ) / 5814
GCD(9, 646) = 5814 / 5814
GCD(9, 646) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 245
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
GCD(1, 245) = 245 / 245
GCD(1, 245) = 1
GCD of 927, 387, 646, 245 is 1
