Given numbers are 498, 128, 197, 385

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

Apply this formula for all numbers.

Step1:

LCM(498, 128) = 31872

GCD(498, 128) = ( 498 x 128 ) / 31872

= 498 / 128

= 498

Step2:

LCM(2, 197) = 394

GCD(2, 197) = ( 2 x 197 ) / 394

= 2 / 197

= 2

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 498, 128, 197, 385 is 1
