Given numbers are 343, 405, 297, 897

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

Apply this formula for all numbers.

Step1:

LCM(343, 405) = 138915

GCD(343, 405) = ( 343 x 405 ) / 138915

= 343 / 405

= 343

Step2:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

Step3:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

So, Greatest Common Divisor of 343, 405, 297, 897 is 1
