Greatest Common Divisior
We found the divisors of 338, 915, 397, 158 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 338, 915, 397, 158 is 1.
Therefore, GCD of numbers 338, 915, 397, 158 is 1
Given Input Data is 338, 915, 397, 158
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 338 is 2 x 13 x 13
Prime Factorization of 915 is 3 x 5 x 61
Prime Factorization of 397 is 397
Prime Factorization of 158 is 2 x 79
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(338, 915) = 309270
GCD(338, 915) = ( 338 x 915 ) / 309270
GCD(338, 915) = 309270 / 309270
GCD(338, 915) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 397
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
GCD(1, 397) = 397 / 397
GCD(1, 397) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 158
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
GCD(1, 158) = 158 / 158
GCD(1, 158) = 1
GCD of 338, 915, 397, 158 is 1
