Given numbers are 254, 865, 687, 439

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

Apply this formula for all numbers.

Step1:

LCM(254, 865) = 219710

GCD(254, 865) = ( 254 x 865 ) / 219710

= 254 / 865

= 254

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 254, 865, 687, 439 is 1
