Given numbers are 247, 189, 321

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

Apply this formula for all numbers.

Step1:

LCM(247, 189) = 46683

GCD(247, 189) = ( 247 x 189 ) / 46683

= 247 / 189

= 247

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 247, 189, 321 is 1
