Given numbers are 243, 981, 349, 255

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

Apply this formula for all numbers.

Step1:

LCM(243, 981) = 26487

GCD(243, 981) = ( 243 x 981 ) / 26487

= 243 / 981

= 243

Step2:

LCM(9, 349) = 3141

GCD(9, 349) = ( 9 x 349 ) / 3141

= 9 / 349

= 9

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 243, 981, 349, 255 is 1
