Therefore, GCD of numbers 515, 545, 128 is 1

Given Input Data is 515, 545, 128

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

Prime Factorization of 515 is 5 x 103

Prime Factorization of 545 is 5 x 109

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

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, 545) = 56135

GCD(515, 545) = ( 515 x 545 ) / 56135

GCD(515, 545) = 280675 / 56135

GCD(515, 545) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 128

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

LCM(5, 128) = 640

GCD(5, 128) = ( 5 x 128 ) / 640

GCD(5, 128) = 640 / 640

GCD(5, 128) = 1

GCD of 515, 545, 128 is 1
