Therefore, GCD of numbers 39, 645, 469, 495 is 1

Given Input Data is 39, 645, 469, 495

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 469 is 7 x 67

Prime Factorization of 495 is 3 x 3 x 5 x 11

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(39, 645) = 8385

GCD(39, 645) = ( 39 x 645 ) / 8385

GCD(39, 645) = 25155 / 8385

GCD(39, 645) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 469

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

LCM(3, 469) = 1407

GCD(3, 469) = ( 3 x 469 ) / 1407

GCD(3, 469) = 1407 / 1407

GCD(3, 469) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 495

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

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

GCD(1, 495) = 495 / 495

GCD(1, 495) = 1

GCD of 39, 645, 469, 495 is 1
