Greatest Common Divisior
We found the divisors of 393, 664, 38, 490 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 393, 664, 38, 490 is 1.
Therefore, GCD of numbers 393, 664, 38, 490 is 1
Given Input Data is 393, 664, 38, 490
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 393 is 3 x 131
Prime Factorization of 664 is 2 x 2 x 2 x 83
Prime Factorization of 38 is 2 x 19
Prime Factorization of 490 is 2 x 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(393, 664) = 260952
GCD(393, 664) = ( 393 x 664 ) / 260952
GCD(393, 664) = 260952 / 260952
GCD(393, 664) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 38
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
GCD(1, 38) = 38 / 38
GCD(1, 38) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 490
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
GCD(1, 490) = 490 / 490
GCD(1, 490) = 1
GCD of 393, 664, 38, 490 is 1
