Given numbers are 621, 609, 685, 353

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 609 are 3 x 7 x 29

Prime factors of 685 are 5 x 137

Prime factors of 353 are 353

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

Given numbers are 621, 609, 685, 353

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

Apply this formula for all numbers.

Step1:

LCM(621, 609) = 126063

GCD(621, 609) = ( 621 x 609 ) / 126063

= 621 / 609

= 621

Step2:

LCM(3, 685) = 2055

GCD(3, 685) = ( 3 x 685 ) / 2055

= 3 / 685

= 3

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 621, 609, 685, 353 is 1
