Given numbers are 381, 455, 201

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

Apply this formula for all numbers.

Step1:

LCM(381, 455) = 173355

GCD(381, 455) = ( 381 x 455 ) / 173355

= 381 / 455

= 381

Step2:

LCM(1, 201) = 201

GCD(1, 201) = ( 1 x 201 ) / 201

= 1 / 201

= 1

So, Greatest Common Divisor of 381, 455, 201 is 1
