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

Apply this formula for all numbers.

Step1:

LCM(428, 822) = 175908

GCD(428, 822) = ( 428 x 822 ) / 175908

= 428 / 822

= 428

Step2:

LCM(2, 166) = 166

GCD(2, 166) = ( 2 x 166 ) / 166

= 2 / 166

= 2

Step3:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

So, Greatest Common Divisor of 428, 822, 166, 668 is 2
