Therefore, GCD of numbers 830, 328, 419, 258 is 1

Given Input Data is 830, 328, 419, 258

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

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 328 is 2 x 2 x 2 x 41

Prime Factorization of 419 is 419

Prime Factorization of 258 is 2 x 3 x 43

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(830, 328) = 136120

GCD(830, 328) = ( 830 x 328 ) / 136120

GCD(830, 328) = 272240 / 136120

GCD(830, 328) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 419

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

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

GCD(2, 419) = 838 / 838

GCD(2, 419) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 258

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

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

GCD(1, 258) = 258 / 258

GCD(1, 258) = 1

GCD of 830, 328, 419, 258 is 1
