Given numbers are 688, 568, 102, 218

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

Apply this formula for all numbers.

Step1:

LCM(688, 568) = 48848

GCD(688, 568) = ( 688 x 568 ) / 48848

= 688 / 568

= 688

Step2:

LCM(8, 102) = 408

GCD(8, 102) = ( 8 x 102 ) / 408

= 8 / 102

= 8

Step3:

LCM(2, 218) = 218

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

= 2 / 218

= 2

So, Greatest Common Divisor of 688, 568, 102, 218 is 2
