Given numbers are 243, 247, 47

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

Apply this formula for all numbers.

Step1:

LCM(243, 247) = 60021

GCD(243, 247) = ( 243 x 247 ) / 60021

= 243 / 247

= 243

Step2:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

So, Greatest Common Divisor of 243, 247, 47 is 1
