Given numbers are 438, 286, 930, 218

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

Apply this formula for all numbers.

Step1:

LCM(438, 286) = 62634

GCD(438, 286) = ( 438 x 286 ) / 62634

= 438 / 286

= 438

Step2:

LCM(2, 930) = 930

GCD(2, 930) = ( 2 x 930 ) / 930

= 2 / 930

= 2

Step3:

LCM(2, 218) = 218

GCD(2, 218) = ( 2 x 218 ) / 218

= 2 / 218

= 2

So, Greatest Common Divisor of 438, 286, 930, 218 is 2
