Given numbers are 257, 397, 520, 833

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

Apply this formula for all numbers.

Step1:

LCM(257, 397) = 102029

GCD(257, 397) = ( 257 x 397 ) / 102029

= 257 / 397

= 257

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

So, Greatest Common Divisor of 257, 397, 520, 833 is 1
