Given numbers are 170, 377, 391

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

Apply this formula for all numbers.

Step1:

LCM(170, 377) = 64090

GCD(170, 377) = ( 170 x 377 ) / 64090

= 170 / 377

= 170

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 170, 377, 391 is 1
