We found the divisors of 159, 550, 46, 398 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 159, 550, 46, 398 is 1.

Therefore, GCD of numbers 159, 550, 46, 398 is 1

Given Input Data is 159, 550, 46, 398

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 159 is 3 x 53

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 46 is 2 x 23

Prime Factorization of 398 is 2 x 199

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(159, 550) = 87450

GCD(159, 550) = ( 159 x 550 ) / 87450

GCD(159, 550) = 87450 / 87450

GCD(159, 550) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 46

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 46) = 46

GCD(1, 46) = ( 1 x 46 ) / 46

GCD(1, 46) = 46 / 46

GCD(1, 46) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 398

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

GCD(1, 398) = 398 / 398

GCD(1, 398) = 1

GCD of 159, 550, 46, 398 is 1
