Greatest Common Divisior
We found the divisors of 247, 127, 903, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 127, 903, 646 is 1.
Therefore, GCD of numbers 247, 127, 903, 646 is 1
Given Input Data is 247, 127, 903, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 127 is 127
Prime Factorization of 903 is 3 x 7 x 43
Prime Factorization of 646 is 2 x 17 x 19
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(247, 127) = 31369
GCD(247, 127) = ( 247 x 127 ) / 31369
GCD(247, 127) = 31369 / 31369
GCD(247, 127) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 903
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
GCD(1, 903) = 903 / 903
GCD(1, 903) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
GCD(1, 646) = 646 / 646
GCD(1, 646) = 1
GCD of 247, 127, 903, 646 is 1
