Given numbers are 287, 881, 343, 285

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

Apply this formula for all numbers.

Step1:

LCM(287, 881) = 252847

GCD(287, 881) = ( 287 x 881 ) / 252847

= 287 / 881

= 287

Step2:

LCM(1, 343) = 343

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

= 1 / 343

= 1

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 287, 881, 343, 285 is 1
