Given numbers are 381, 323, 820

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

Apply this formula for all numbers.

Step1:

LCM(381, 323) = 123063

GCD(381, 323) = ( 381 x 323 ) / 123063

= 381 / 323

= 381

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 381, 323, 820 is 1
