Given numbers are 770, 230, 684, 620

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

Apply this formula for all numbers.

Step1:

LCM(770, 230) = 17710

GCD(770, 230) = ( 770 x 230 ) / 17710

= 770 / 230

= 770

Step2:

LCM(10, 684) = 3420

GCD(10, 684) = ( 10 x 684 ) / 3420

= 10 / 684

= 10

Step3:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

So, Greatest Common Divisor of 770, 230, 684, 620 is 2
