Given Input Data is 126, 258, 415, 492

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

Prime Factorization of 126 is 2 x 3 x 3 x 7

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 415 is 5 x 83

Prime Factorization of 492 is 2 x 2 x 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(126, 258) = 5418

GCD(126, 258) = ( 126 x 258 ) / 5418

GCD(126, 258) = 32508 / 5418

GCD(126, 258) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 415

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

LCM(6, 415) = 2490

GCD(6, 415) = ( 6 x 415 ) / 2490

GCD(6, 415) = 2490 / 2490

GCD(6, 415) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 492

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

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

GCD(1, 492) = 492 / 492

GCD(1, 492) = 1

GCD of 126, 258, 415, 492 is 1
