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

Apply this formula for all numbers.

Step1:

LCM(642, 774) = 82818

GCD(642, 774) = ( 642 x 774 ) / 82818

= 642 / 774

= 642

Step2:

LCM(6, 844) = 2532

GCD(6, 844) = ( 6 x 844 ) / 2532

= 6 / 844

= 6

Step3:

LCM(2, 708) = 708

GCD(2, 708) = ( 2 x 708 ) / 708

= 2 / 708

= 2

So, Greatest Common Divisor of 642, 774, 844, 708 is 2
