1, 2, 4, 97, 194, 388
Greatest Common Divisior
We found the divisors of 426, 345, 388 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 426, 345, 388 is 1.
Therefore, GCD of numbers 426, 345, 388 is 1
Given Input Data is 426, 345, 388
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 426 is 2 x 3 x 71
Prime Factorization of 345 is 3 x 5 x 23
Prime Factorization of 388 is 2 x 2 x 97
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(426, 345) = 48990
GCD(426, 345) = ( 426 x 345 ) / 48990
GCD(426, 345) = 146970 / 48990
GCD(426, 345) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 388
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 388) = 1164
GCD(3, 388) = ( 3 x 388 ) / 1164
GCD(3, 388) = 1164 / 1164
GCD(3, 388) = 1
GCD of 426, 345, 388 is 1
