Given numbers are 406, 247, 430

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

Apply this formula for all numbers.

Step1:

LCM(406, 247) = 100282

GCD(406, 247) = ( 406 x 247 ) / 100282

= 406 / 247

= 406

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 406, 247, 430 is 1
