Therefore, GCD of numbers 60, 280, 273, 391 is 1

Given Input Data is 60, 280, 273, 391

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

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 391 is 17 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(60, 280) = 840

GCD(60, 280) = ( 60 x 280 ) / 840

GCD(60, 280) = 16800 / 840

GCD(60, 280) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 273

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

LCM(20, 273) = 5460

GCD(20, 273) = ( 20 x 273 ) / 5460

GCD(20, 273) = 5460 / 5460

GCD(20, 273) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 60, 280, 273, 391 is 1
