Given numbers are 495, 407, 645, 493

The list of prime factors of all numbers are

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 407 are 11 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 493 are 17 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 495, 407, 645, 493

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(495, 407) = 18315

GCD(495, 407) = ( 495 x 407 ) / 18315

= 495 / 407

= 495

Step2:

LCM(11, 645) = 7095

GCD(11, 645) = ( 11 x 645 ) / 7095

= 11 / 645

= 11

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 495, 407, 645, 493 is 1
