Therefore, GCD of numbers 220, 425, 566, 623 is 1

Given Input Data is 220, 425, 566, 623

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 566 is 2 x 283

Prime Factorization of 623 is 7 x 89

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(220, 425) = 18700

GCD(220, 425) = ( 220 x 425 ) / 18700

GCD(220, 425) = 93500 / 18700

GCD(220, 425) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 566

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

LCM(5, 566) = 2830

GCD(5, 566) = ( 5 x 566 ) / 2830

GCD(5, 566) = 2830 / 2830

GCD(5, 566) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 623

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

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

GCD(1, 623) = 623 / 623

GCD(1, 623) = 1

GCD of 220, 425, 566, 623 is 1
