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

Apply this formula for all numbers.

Step1:

LCM(646, 884) = 16796

GCD(646, 884) = ( 646 x 884 ) / 16796

= 646 / 884

= 646

Step2:

LCM(34, 668) = 11356

GCD(34, 668) = ( 34 x 668 ) / 11356

= 34 / 668

= 34

Step3:

LCM(2, 740) = 740

GCD(2, 740) = ( 2 x 740 ) / 740

= 2 / 740

= 2

So, Greatest Common Divisor of 646, 884, 668, 740 is 2
