Given numbers are 517, 320, 509, 788

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

Apply this formula for all numbers.

Step1:

LCM(517, 320) = 165440

GCD(517, 320) = ( 517 x 320 ) / 165440

= 517 / 320

= 517

Step2:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

Step3:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

So, Greatest Common Divisor of 517, 320, 509, 788 is 1
