Given numbers are 209, 455, 343, 514

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

Apply this formula for all numbers.

Step1:

LCM(209, 455) = 95095

GCD(209, 455) = ( 209 x 455 ) / 95095

= 209 / 455

= 209

Step2:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

Step3:

LCM(1, 514) = 514

GCD(1, 514) = ( 1 x 514 ) / 514

= 1 / 514

= 1

So, Greatest Common Divisor of 209, 455, 343, 514 is 1
