Given numbers are 218, 618, 620

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

Apply this formula for all numbers.

Step1:

LCM(218, 618) = 67362

GCD(218, 618) = ( 218 x 618 ) / 67362

= 218 / 618

= 218

Step2:

LCM(2, 620) = 620

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

= 2 / 620

= 2

So, Greatest Common Divisor of 218, 618, 620 is 2
