Given numbers are 257, 709, 545, 479

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

Apply this formula for all numbers.

Step1:

LCM(257, 709) = 182213

GCD(257, 709) = ( 257 x 709 ) / 182213

= 257 / 709

= 257

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 257, 709, 545, 479 is 1
