Given numbers are 856, 724, 811

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

Apply this formula for all numbers.

Step1:

LCM(856, 724) = 154936

GCD(856, 724) = ( 856 x 724 ) / 154936

= 856 / 724

= 856

Step2:

LCM(4, 811) = 3244

GCD(4, 811) = ( 4 x 811 ) / 3244

= 4 / 811

= 4

So, Greatest Common Divisor of 856, 724, 811 is 1
