Given Input Data is 366, 858, 647

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

Prime Factorization of 366 is 2 x 3 x 61

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 647 is 647

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(366, 858) = 52338

GCD(366, 858) = ( 366 x 858 ) / 52338

GCD(366, 858) = 314028 / 52338

GCD(366, 858) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 647

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

LCM(6, 647) = 3882

GCD(6, 647) = ( 6 x 647 ) / 3882

GCD(6, 647) = 3882 / 3882

GCD(6, 647) = 1

GCD of 366, 858, 647 is 1
