Given numbers are 399, 864, 64, 238

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

Apply this formula for all numbers.

Step1:

LCM(399, 864) = 114912

GCD(399, 864) = ( 399 x 864 ) / 114912

= 399 / 864

= 399

Step2:

LCM(3, 64) = 192

GCD(3, 64) = ( 3 x 64 ) / 192

= 3 / 64

= 3

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 399, 864, 64, 238 is 1
