Given numbers are 811, 345, 165

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

Apply this formula for all numbers.

Step1:

LCM(811, 345) = 279795

GCD(811, 345) = ( 811 x 345 ) / 279795

= 811 / 345

= 811

Step2:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 811, 345, 165 is 1
