Given Input Data is 840, 546, 166, 571

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

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

Prime Factorization of 166 is 2 x 83

Prime Factorization of 571 is 571

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(840, 546) = 10920

GCD(840, 546) = ( 840 x 546 ) / 10920

GCD(840, 546) = 458640 / 10920

GCD(840, 546) = 42

Step2:

Here we consider the GCD from the above i.e. 42 as first number and the next as 166

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

LCM(42, 166) = 3486

GCD(42, 166) = ( 42 x 166 ) / 3486

GCD(42, 166) = 6972 / 3486

GCD(42, 166) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 571

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

LCM(2, 571) = 1142

GCD(2, 571) = ( 2 x 571 ) / 1142

GCD(2, 571) = 1142 / 1142

GCD(2, 571) = 1

GCD of 840, 546, 166, 571 is 1
