Given numbers are 639, 646, 339

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

Apply this formula for all numbers.

Step1:

LCM(639, 646) = 412794

GCD(639, 646) = ( 639 x 646 ) / 412794

= 639 / 646

= 639

Step2:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 639, 646, 339 is 1
