Therefore, GCD of numbers 518, 259, 55, 105 is 1

Given Input Data is 518, 259, 55, 105

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

Prime Factorization of 518 is 2 x 7 x 37

Prime Factorization of 259 is 7 x 37

Prime Factorization of 55 is 5 x 11

Prime Factorization of 105 is 3 x 5 x 7

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(518, 259) = 518

GCD(518, 259) = ( 518 x 259 ) / 518

GCD(518, 259) = 134162 / 518

GCD(518, 259) = 259

Step2:

Here we consider the GCD from the above i.e. 259 as first number and the next as 55

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

LCM(259, 55) = 14245

GCD(259, 55) = ( 259 x 55 ) / 14245

GCD(259, 55) = 14245 / 14245

GCD(259, 55) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 105

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

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

GCD(1, 105) = 105 / 105

GCD(1, 105) = 1

GCD of 518, 259, 55, 105 is 1
