Given Input Data is 858, 481, 265, 647

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

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

Prime Factorization of 481 is 13 x 37

Prime Factorization of 265 is 5 x 53

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(858, 481) = 31746

GCD(858, 481) = ( 858 x 481 ) / 31746

GCD(858, 481) = 412698 / 31746

GCD(858, 481) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 265

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

LCM(13, 265) = 3445

GCD(13, 265) = ( 13 x 265 ) / 3445

GCD(13, 265) = 3445 / 3445

GCD(13, 265) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 647

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

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

GCD(1, 647) = 647 / 647

GCD(1, 647) = 1

GCD of 858, 481, 265, 647 is 1
