Given numbers are 811, 686, 856, 195

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

Apply this formula for all numbers.

Step1:

LCM(811, 686) = 556346

GCD(811, 686) = ( 811 x 686 ) / 556346

= 811 / 686

= 811

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 811, 686, 856, 195 is 1
