Therefore, GCD of numbers 280, 520, 223 is 1

Given Input Data is 280, 520, 223

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 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 223 is 223

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, 520) = 3640

GCD(280, 520) = ( 280 x 520 ) / 3640

GCD(280, 520) = 145600 / 3640

GCD(280, 520) = 40

Step2:

Here we consider the GCD from the above i.e. 40 as first number and the next as 223

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

LCM(40, 223) = 8920

GCD(40, 223) = ( 40 x 223 ) / 8920

GCD(40, 223) = 8920 / 8920

GCD(40, 223) = 1

GCD of 280, 520, 223 is 1
