Given numbers are 344, 646, 676, 679

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

Apply this formula for all numbers.

Step1:

LCM(344, 646) = 111112

GCD(344, 646) = ( 344 x 646 ) / 111112

= 344 / 646

= 344

Step2:

LCM(2, 676) = 676

GCD(2, 676) = ( 2 x 676 ) / 676

= 2 / 676

= 2

Step3:

LCM(2, 679) = 1358

GCD(2, 679) = ( 2 x 679 ) / 1358

= 2 / 679

= 2

So, Greatest Common Divisor of 344, 646, 676, 679 is 1
