Given numbers are 646, 479, 345

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

Apply this formula for all numbers.

Step1:

LCM(646, 479) = 309434

GCD(646, 479) = ( 646 x 479 ) / 309434

= 646 / 479

= 646

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 646, 479, 345 is 1
