Given numbers are 678, 774, 115, 256

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

Apply this formula for all numbers.

Step1:

LCM(678, 774) = 87462

GCD(678, 774) = ( 678 x 774 ) / 87462

= 678 / 774

= 678

Step2:

LCM(6, 115) = 690

GCD(6, 115) = ( 6 x 115 ) / 690

= 6 / 115

= 6

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 678, 774, 115, 256 is 1
