Given numbers are 819, 709, 855, 285

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

Apply this formula for all numbers.

Step1:

LCM(819, 709) = 580671

GCD(819, 709) = ( 819 x 709 ) / 580671

= 819 / 709

= 819

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 819, 709, 855, 285 is 1
