Given numbers are 861, 855, 354, 516

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

Apply this formula for all numbers.

Step1:

LCM(861, 855) = 245385

GCD(861, 855) = ( 861 x 855 ) / 245385

= 861 / 855

= 861

Step2:

LCM(3, 354) = 354

GCD(3, 354) = ( 3 x 354 ) / 354

= 3 / 354

= 3

Step3:

LCM(3, 516) = 516

GCD(3, 516) = ( 3 x 516 ) / 516

= 3 / 516

= 3

So, Greatest Common Divisor of 861, 855, 354, 516 is 3
