Given numbers are 209, 646, 297, 344

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

Apply this formula for all numbers.

Step1:

LCM(209, 646) = 7106

GCD(209, 646) = ( 209 x 646 ) / 7106

= 209 / 646

= 209

Step2:

LCM(19, 297) = 5643

GCD(19, 297) = ( 19 x 297 ) / 5643

= 19 / 297

= 19

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 209, 646, 297, 344 is 1
