Given numbers are 405, 609, 378, 613

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 609 are 3 x 7 x 29

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 613 are 613

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

Given numbers are 405, 609, 378, 613

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

Apply this formula for all numbers.

Step1:

LCM(405, 609) = 82215

GCD(405, 609) = ( 405 x 609 ) / 82215

= 405 / 609

= 405

Step2:

LCM(3, 378) = 378

GCD(3, 378) = ( 3 x 378 ) / 378

= 3 / 378

= 3

Step3:

LCM(3, 613) = 1839

GCD(3, 613) = ( 3 x 613 ) / 1839

= 3 / 613

= 3

So, Greatest Common Divisor of 405, 609, 378, 613 is 1
