Given numbers are 678, 254, 863, 388

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

Apply this formula for all numbers.

Step1:

LCM(678, 254) = 86106

GCD(678, 254) = ( 678 x 254 ) / 86106

= 678 / 254

= 678

Step2:

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

= 2 / 863

= 2

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 678, 254, 863, 388 is 1
