Greatest Common Divisior
We found the divisors of 639, 283, 753, 399 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 283, 753, 399 is 1.
Therefore, GCD of numbers 639, 283, 753, 399 is 1
Given Input Data is 639, 283, 753, 399
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 283 is 283
Prime Factorization of 753 is 3 x 251
Prime Factorization of 399 is 3 x 7 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(639, 283) = 180837
GCD(639, 283) = ( 639 x 283 ) / 180837
GCD(639, 283) = 180837 / 180837
GCD(639, 283) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 753
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 753) = 753
GCD(1, 753) = ( 1 x 753 ) / 753
GCD(1, 753) = 753 / 753
GCD(1, 753) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 399
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
GCD(1, 399) = 399 / 399
GCD(1, 399) = 1
GCD of 639, 283, 753, 399 is 1
