Given numbers are 428, 321, 170, 682

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

Apply this formula for all numbers.

Step1:

LCM(428, 321) = 1284

GCD(428, 321) = ( 428 x 321 ) / 1284

= 428 / 321

= 428

Step2:

LCM(107, 170) = 18190

GCD(107, 170) = ( 107 x 170 ) / 18190

= 107 / 170

= 107

Step3:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

So, Greatest Common Divisor of 428, 321, 170, 682 is 1
