Greatest Common Divisior
We found the divisors of 842, 958, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 842, 958, 646 is 2.
Therefore, GCD of numbers 842, 958, 646 is 2
Given Input Data is 842, 958, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 842 is 2 x 421
Prime Factorization of 958 is 2 x 479
Prime Factorization of 646 is 2 x 17 x 19
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(842, 958) = 403318
GCD(842, 958) = ( 842 x 958 ) / 403318
GCD(842, 958) = 806636 / 403318
GCD(842, 958) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
GCD(2, 646) = 1292 / 646
GCD(2, 646) = 2
GCD of 842, 958, 646 is 2
