Given numbers are 166, 428, 604, 670

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

Apply this formula for all numbers.

Step1:

LCM(166, 428) = 35524

GCD(166, 428) = ( 166 x 428 ) / 35524

= 166 / 428

= 166

Step2:

LCM(2, 604) = 604

GCD(2, 604) = ( 2 x 604 ) / 604

= 2 / 604

= 2

Step3:

LCM(2, 670) = 670

GCD(2, 670) = ( 2 x 670 ) / 670

= 2 / 670

= 2

So, Greatest Common Divisor of 166, 428, 604, 670 is 2
