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

Apply this formula for all numbers.

Step1:

LCM(312, 786) = 40872

GCD(312, 786) = ( 312 x 786 ) / 40872

= 312 / 786

= 312

Step2:

LCM(6, 442) = 1326

GCD(6, 442) = ( 6 x 442 ) / 1326

= 6 / 442

= 6

Step3:

LCM(2, 770) = 770

GCD(2, 770) = ( 2 x 770 ) / 770

= 2 / 770

= 2

So, Greatest Common Divisor of 312, 786, 442, 770 is 2
