Therefore, GCD of numbers 555, 203, 43, 123 is 1

Given Input Data is 555, 203, 43, 123

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 203 is 7 x 29

Prime Factorization of 43 is 43

Prime Factorization of 123 is 3 x 41

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(555, 203) = 112665

GCD(555, 203) = ( 555 x 203 ) / 112665

GCD(555, 203) = 112665 / 112665

GCD(555, 203) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

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

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 123

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

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

GCD(1, 123) = 123 / 123

GCD(1, 123) = 1

GCD of 555, 203, 43, 123 is 1
