Given numbers are 457, 287, 171, 388

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

Apply this formula for all numbers.

Step1:

LCM(457, 287) = 131159

GCD(457, 287) = ( 457 x 287 ) / 131159

= 457 / 287

= 457

Step2:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 457, 287, 171, 388 is 1
