Given numbers are 630, 404, 420, 866

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

Apply this formula for all numbers.

Step1:

LCM(630, 404) = 127260

GCD(630, 404) = ( 630 x 404 ) / 127260

= 630 / 404

= 630

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 866) = 866

GCD(2, 866) = ( 2 x 866 ) / 866

= 2 / 866

= 2

So, Greatest Common Divisor of 630, 404, 420, 866 is 2
