Greatest Common Divisior
We found the divisors of 423, 639, 993 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 423, 639, 993 is 3.
Therefore, GCD of numbers 423, 639, 993 is 3
Given Input Data is 423, 639, 993
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 423 is 3 x 3 x 47
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 993 is 3 x 331
Highest common occurrences in the given inputs are 31
Multiplying them we get the GCD as 3
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(423, 639) = 30033
GCD(423, 639) = ( 423 x 639 ) / 30033
GCD(423, 639) = 270297 / 30033
GCD(423, 639) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 993
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 993) = 2979
GCD(9, 993) = ( 9 x 993 ) / 2979
GCD(9, 993) = 8937 / 2979
GCD(9, 993) = 3
GCD of 423, 639, 993 is 3
