Given numbers are 285, 438, 188, 286

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

Apply this formula for all numbers.

Step1:

LCM(285, 438) = 41610

GCD(285, 438) = ( 285 x 438 ) / 41610

= 285 / 438

= 285

Step2:

LCM(3, 188) = 564

GCD(3, 188) = ( 3 x 188 ) / 564

= 3 / 188

= 3

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 285, 438, 188, 286 is 1
