Given numbers are 243, 343, 817, 847

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

Apply this formula for all numbers.

Step1:

LCM(243, 343) = 83349

GCD(243, 343) = ( 243 x 343 ) / 83349

= 243 / 343

= 243

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 243, 343, 817, 847 is 1
