Given numbers are 257, 503, 860

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

Apply this formula for all numbers.

Step1:

LCM(257, 503) = 129271

GCD(257, 503) = ( 257 x 503 ) / 129271

= 257 / 503

= 257

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 257, 503, 860 is 1
