Given numbers are 639, 310, 343

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

Apply this formula for all numbers.

Step1:

LCM(639, 310) = 198090

GCD(639, 310) = ( 639 x 310 ) / 198090

= 639 / 310

= 639

Step2:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

So, Greatest Common Divisor of 639, 310, 343 is 1
