Given numbers are 388, 178, 191, 646

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

Apply this formula for all numbers.

Step1:

LCM(388, 178) = 34532

GCD(388, 178) = ( 388 x 178 ) / 34532

= 388 / 178

= 388

Step2:

LCM(2, 191) = 382

GCD(2, 191) = ( 2 x 191 ) / 382

= 2 / 191

= 2

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 388, 178, 191, 646 is 1
