Therefore, GCD of numbers 515, 170, 43, 115 is 1

Given Input Data is 515, 170, 43, 115

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

Prime Factorization of 515 is 5 x 103

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 43 is 43

Prime Factorization of 115 is 5 x 23

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(515, 170) = 17510

GCD(515, 170) = ( 515 x 170 ) / 17510

GCD(515, 170) = 87550 / 17510

GCD(515, 170) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 43

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

LCM(5, 43) = 215

GCD(5, 43) = ( 5 x 43 ) / 215

GCD(5, 43) = 215 / 215

GCD(5, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 115

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

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

GCD(1, 115) = 115 / 115

GCD(1, 115) = 1

GCD of 515, 170, 43, 115 is 1
