Greatest Common Divisior
We found the divisors of 643, 496, 506, 318 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 496, 506, 318 is 1.
Therefore, GCD of numbers 643, 496, 506, 318 is 1
Given Input Data is 643, 496, 506, 318
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 496 is 2 x 2 x 2 x 2 x 31
Prime Factorization of 506 is 2 x 11 x 23
Prime Factorization of 318 is 2 x 3 x 53
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(643, 496) = 318928
GCD(643, 496) = ( 643 x 496 ) / 318928
GCD(643, 496) = 318928 / 318928
GCD(643, 496) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 506
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
GCD(1, 506) = 506 / 506
GCD(1, 506) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 318
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
GCD(1, 318) = 318 / 318
GCD(1, 318) = 1
GCD of 643, 496, 506, 318 is 1
