Given numbers are 398, 961, 170

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

Apply this formula for all numbers.

Step1:

LCM(398, 961) = 382478

GCD(398, 961) = ( 398 x 961 ) / 382478

= 398 / 961

= 398

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 398, 961, 170 is 1
