Given numbers are 428, 670, 329

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

Apply this formula for all numbers.

Step1:

LCM(428, 670) = 143380

GCD(428, 670) = ( 428 x 670 ) / 143380

= 428 / 670

= 428

Step2:

LCM(2, 329) = 658

GCD(2, 329) = ( 2 x 329 ) / 658

= 2 / 329

= 2

So, Greatest Common Divisor of 428, 670, 329 is 1
