Given numbers are 516, 405, 390, 568

The list of prime factors of all numbers are

Prime factors of 516 are 2 x 2 x 3 x 43

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 568 are 2 x 2 x 2 x 71

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

Given numbers are 516, 405, 390, 568

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

Apply this formula for all numbers.

Step1:

LCM(516, 405) = 69660

GCD(516, 405) = ( 516 x 405 ) / 69660

= 516 / 405

= 516

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 568) = 1704

GCD(3, 568) = ( 3 x 568 ) / 1704

= 3 / 568

= 3

So, Greatest Common Divisor of 516, 405, 390, 568 is 1
