Given numbers are 630, 392, 678, 340

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

Apply this formula for all numbers.

Step1:

LCM(630, 392) = 17640

GCD(630, 392) = ( 630 x 392 ) / 17640

= 630 / 392

= 630

Step2:

LCM(14, 678) = 4746

GCD(14, 678) = ( 14 x 678 ) / 4746

= 14 / 678

= 14

Step3:

LCM(2, 340) = 340

GCD(2, 340) = ( 2 x 340 ) / 340

= 2 / 340

= 2

So, Greatest Common Divisor of 630, 392, 678, 340 is 2
