Given numbers are 398, 774, 447

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

Apply this formula for all numbers.

Step1:

LCM(398, 774) = 154026

GCD(398, 774) = ( 398 x 774 ) / 154026

= 398 / 774

= 398

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

So, Greatest Common Divisor of 398, 774, 447 is 1
