Given numbers are 285, 717, 495, 830

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

Apply this formula for all numbers.

Step1:

LCM(285, 717) = 68115

GCD(285, 717) = ( 285 x 717 ) / 68115

= 285 / 717

= 285

Step2:

LCM(3, 495) = 495

GCD(3, 495) = ( 3 x 495 ) / 495

= 3 / 495

= 3

Step3:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

So, Greatest Common Divisor of 285, 717, 495, 830 is 1
