Given numbers are 680, 560, 405, 252

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Given numbers are 680, 560, 405, 252

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

Apply this formula for all numbers.

Step1:

LCM(680, 560) = 9520

GCD(680, 560) = ( 680 x 560 ) / 9520

= 680 / 560

= 680

Step2:

LCM(40, 405) = 3240

GCD(40, 405) = ( 40 x 405 ) / 3240

= 40 / 405

= 40

Step3:

LCM(5, 252) = 1260

GCD(5, 252) = ( 5 x 252 ) / 1260

= 5 / 252

= 5

So, Greatest Common Divisor of 680, 560, 405, 252 is 1
