Given numbers are 398, 836, 655

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

Apply this formula for all numbers.

Step1:

LCM(398, 836) = 166364

GCD(398, 836) = ( 398 x 836 ) / 166364

= 398 / 836

= 398

Step2:

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

= 2 / 655

= 2

So, Greatest Common Divisor of 398, 836, 655 is 1
