Greatest Common Divisior
We found the divisors of 639, 960, 46, 815 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 960, 46, 815 is 1.
Therefore, GCD of numbers 639, 960, 46, 815 is 1
Given Input Data is 639, 960, 46, 815
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 960 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5
Prime Factorization of 46 is 2 x 23
Prime Factorization of 815 is 5 x 163
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(639, 960) = 204480
GCD(639, 960) = ( 639 x 960 ) / 204480
GCD(639, 960) = 613440 / 204480
GCD(639, 960) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 46
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 46) = 138
GCD(3, 46) = ( 3 x 46 ) / 138
GCD(3, 46) = 138 / 138
GCD(3, 46) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 815
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
GCD(1, 815) = 815 / 815
GCD(1, 815) = 1
GCD of 639, 960, 46, 815 is 1
