1, 3, 163, 489
Greatest Common Divisior
We found the divisors of 238, 426, 55, 489 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 238, 426, 55, 489 is 1.
Therefore, GCD of numbers 238, 426, 55, 489 is 1
Given Input Data is 238, 426, 55, 489
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 238 is 2 x 7 x 17
Prime Factorization of 426 is 2 x 3 x 71
Prime Factorization of 55 is 5 x 11
Prime Factorization of 489 is 3 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(238, 426) = 50694
GCD(238, 426) = ( 238 x 426 ) / 50694
GCD(238, 426) = 101388 / 50694
GCD(238, 426) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 55) = 110
GCD(2, 55) = ( 2 x 55 ) / 110
GCD(2, 55) = 110 / 110
GCD(2, 55) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 489
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
GCD(1, 489) = 489 / 489
GCD(1, 489) = 1
GCD of 238, 426, 55, 489 is 1
