Given numbers are 381, 171, 194, 206

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

Apply this formula for all numbers.

Step1:

LCM(381, 171) = 21717

GCD(381, 171) = ( 381 x 171 ) / 21717

= 381 / 171

= 381

Step2:

LCM(3, 194) = 582

GCD(3, 194) = ( 3 x 194 ) / 582

= 3 / 194

= 3

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 381, 171, 194, 206 is 1
