Given numbers are 438, 285, 919, 216

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

Apply this formula for all numbers.

Step1:

LCM(438, 285) = 41610

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

= 438 / 285

= 438

Step2:

LCM(3, 919) = 2757

GCD(3, 919) = ( 3 x 919 ) / 2757

= 3 / 919

= 3

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 438, 285, 919, 216 is 1
