Therefore, GCD of numbers 280, 985, 224, 460 is 1

Given Input Data is 280, 985, 224, 460

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

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 224 is 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 460 is 2 x 2 x 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(280, 985) = 55160

GCD(280, 985) = ( 280 x 985 ) / 55160

GCD(280, 985) = 275800 / 55160

GCD(280, 985) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 224

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

LCM(5, 224) = 1120

GCD(5, 224) = ( 5 x 224 ) / 1120

GCD(5, 224) = 1120 / 1120

GCD(5, 224) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 460

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

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

GCD(1, 460) = 460 / 460

GCD(1, 460) = 1

GCD of 280, 985, 224, 460 is 1
