Given numbers are 257, 670, 459

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

Apply this formula for all numbers.

Step1:

LCM(257, 670) = 172190

GCD(257, 670) = ( 257 x 670 ) / 172190

= 257 / 670

= 257

Step2:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 257, 670, 459 is 1
