Given numbers are 398, 409, 380

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

Apply this formula for all numbers.

Step1:

LCM(398, 409) = 162782

GCD(398, 409) = ( 398 x 409 ) / 162782

= 398 / 409

= 398

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 398, 409, 380 is 1
