Therefore, GCD of numbers 546, 603, 727, 421 is 1

Given Input Data is 546, 603, 727, 421

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

Prime Factorization of 546 is 2 x 3 x 7 x 13

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 727 is 727

Prime Factorization of 421 is 421

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(546, 603) = 109746

GCD(546, 603) = ( 546 x 603 ) / 109746

GCD(546, 603) = 329238 / 109746

GCD(546, 603) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 727

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

LCM(3, 727) = 2181

GCD(3, 727) = ( 3 x 727 ) / 2181

GCD(3, 727) = 2181 / 2181

GCD(3, 727) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 421

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

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

GCD(1, 421) = 421 / 421

GCD(1, 421) = 1

GCD of 546, 603, 727, 421 is 1
