Given numbers are 861, 816, 560, 839

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

Apply this formula for all numbers.

Step1:

LCM(861, 816) = 234192

GCD(861, 816) = ( 861 x 816 ) / 234192

= 861 / 816

= 861

Step2:

LCM(3, 560) = 1680

GCD(3, 560) = ( 3 x 560 ) / 1680

= 3 / 560

= 3

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 861, 816, 560, 839 is 1
