Therefore, GCD of numbers 220, 671, 243, 542 is 1

Given Input Data is 220, 671, 243, 542

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 671 is 11 x 61

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 542 is 2 x 271

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, 671) = 13420

GCD(220, 671) = ( 220 x 671 ) / 13420

GCD(220, 671) = 147620 / 13420

GCD(220, 671) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 243

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

LCM(11, 243) = 2673

GCD(11, 243) = ( 11 x 243 ) / 2673

GCD(11, 243) = 2673 / 2673

GCD(11, 243) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 542

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

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

GCD(1, 542) = 542 / 542

GCD(1, 542) = 1

GCD of 220, 671, 243, 542 is 1
