Given numbers are 668, 702, 218, 168

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

Apply this formula for all numbers.

Step1:

LCM(668, 702) = 234468

GCD(668, 702) = ( 668 x 702 ) / 234468

= 668 / 702

= 668

Step2:

LCM(2, 218) = 218

GCD(2, 218) = ( 2 x 218 ) / 218

= 2 / 218

= 2

Step3:

LCM(2, 168) = 168

GCD(2, 168) = ( 2 x 168 ) / 168

= 2 / 168

= 2

So, Greatest Common Divisor of 668, 702, 218, 168 is 2
