Given numbers are 678, 636, 210, 417

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

Apply this formula for all numbers.

Step1:

LCM(678, 636) = 71868

GCD(678, 636) = ( 678 x 636 ) / 71868

= 678 / 636

= 678

Step2:

LCM(6, 210) = 210

GCD(6, 210) = ( 6 x 210 ) / 210

= 6 / 210

= 6

Step3:

LCM(6, 417) = 834

GCD(6, 417) = ( 6 x 417 ) / 834

= 6 / 417

= 6

So, Greatest Common Divisor of 678, 636, 210, 417 is 3
