Given numbers are 343, 840, 283, 349

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

Apply this formula for all numbers.

Step1:

LCM(343, 840) = 41160

GCD(343, 840) = ( 343 x 840 ) / 41160

= 343 / 840

= 343

Step2:

LCM(7, 283) = 1981

GCD(7, 283) = ( 7 x 283 ) / 1981

= 7 / 283

= 7

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 343, 840, 283, 349 is 1
