Given numbers are 865, 388, 678

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

Apply this formula for all numbers.

Step1:

LCM(865, 388) = 335620

GCD(865, 388) = ( 865 x 388 ) / 335620

= 865 / 388

= 865

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 865, 388, 678 is 1
