Given numbers are 275, 388, 191, 215

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

Apply this formula for all numbers.

Step1:

LCM(275, 388) = 106700

GCD(275, 388) = ( 275 x 388 ) / 106700

= 275 / 388

= 275

Step2:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 275, 388, 191, 215 is 1
