Therefore, GCD of numbers 145, 285, 73, 275 is 1

Given Input Data is 145, 285, 73, 275

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

Prime Factorization of 145 is 5 x 29

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 73 is 73

Prime Factorization of 275 is 5 x 5 x 11

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(145, 285) = 8265

GCD(145, 285) = ( 145 x 285 ) / 8265

GCD(145, 285) = 41325 / 8265

GCD(145, 285) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 73

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

LCM(5, 73) = 365

GCD(5, 73) = ( 5 x 73 ) / 365

GCD(5, 73) = 365 / 365

GCD(5, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 275

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

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

GCD(1, 275) = 275 / 275

GCD(1, 275) = 1

GCD of 145, 285, 73, 275 is 1
