Given numbers are 406, 545, 429

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

Apply this formula for all numbers.

Step1:

LCM(406, 545) = 221270

GCD(406, 545) = ( 406 x 545 ) / 221270

= 406 / 545

= 406

Step2:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

So, Greatest Common Divisor of 406, 545, 429 is 1
