Given numbers are 256, 520, 478

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

Apply this formula for all numbers.

Step1:

LCM(256, 520) = 16640

GCD(256, 520) = ( 256 x 520 ) / 16640

= 256 / 520

= 256

Step2:

LCM(8, 478) = 1912

GCD(8, 478) = ( 8 x 478 ) / 1912

= 8 / 478

= 8

So, Greatest Common Divisor of 256, 520, 478 is 2
