Given numbers are 257, 981, 817, 539

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

Apply this formula for all numbers.

Step1:

LCM(257, 981) = 252117

GCD(257, 981) = ( 257 x 981 ) / 252117

= 257 / 981

= 257

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 257, 981, 817, 539 is 1
