Greatest Common Divisior
We found the divisors of 257, 973, 928, 647 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 257, 973, 928, 647 is 1.
Therefore, GCD of numbers 257, 973, 928, 647 is 1
Given Input Data is 257, 973, 928, 647
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 257 is 257
Prime Factorization of 973 is 7 x 139
Prime Factorization of 928 is 2 x 2 x 2 x 2 x 2 x 29
Prime Factorization of 647 is 647
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(257, 973) = 250061
GCD(257, 973) = ( 257 x 973 ) / 250061
GCD(257, 973) = 250061 / 250061
GCD(257, 973) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 928
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
GCD(1, 928) = 928 / 928
GCD(1, 928) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 647
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
GCD(1, 647) = 647 / 647
GCD(1, 647) = 1
GCD of 257, 973, 928, 647 is 1
