Therefore, GCD of numbers 481, 518, 770, 623 is 1

Given Input Data is 481, 518, 770, 623

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

Prime Factorization of 481 is 13 x 37

Prime Factorization of 518 is 2 x 7 x 37

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 623 is 7 x 89

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(481, 518) = 6734

GCD(481, 518) = ( 481 x 518 ) / 6734

GCD(481, 518) = 249158 / 6734

GCD(481, 518) = 37

Step2:

Here we consider the GCD from the above i.e. 37 as first number and the next as 770

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

LCM(37, 770) = 28490

GCD(37, 770) = ( 37 x 770 ) / 28490

GCD(37, 770) = 28490 / 28490

GCD(37, 770) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 623

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

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

GCD(1, 623) = 623 / 623

GCD(1, 623) = 1

GCD of 481, 518, 770, 623 is 1
