Given numbers are 498, 285, 434, 391

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

Apply this formula for all numbers.

Step1:

LCM(498, 285) = 47310

GCD(498, 285) = ( 498 x 285 ) / 47310

= 498 / 285

= 498

Step2:

LCM(3, 434) = 1302

GCD(3, 434) = ( 3 x 434 ) / 1302

= 3 / 434

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 498, 285, 434, 391 is 1
