Given numbers are 247, 472, 406

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

Apply this formula for all numbers.

Step1:

LCM(247, 472) = 116584

GCD(247, 472) = ( 247 x 472 ) / 116584

= 247 / 472

= 247

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 247, 472, 406 is 1
