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

Apply this formula for all numbers.

Step1:

LCM(398, 292) = 58108

GCD(398, 292) = ( 398 x 292 ) / 58108

= 398 / 292

= 398

Step2:

LCM(2, 418) = 418

GCD(2, 418) = ( 2 x 418 ) / 418

= 2 / 418

= 2

Step3:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

So, Greatest Common Divisor of 398, 292, 418, 666 is 2
