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

Apply this formula for all numbers.

Step1:

LCM(688, 728) = 62608

GCD(688, 728) = ( 688 x 728 ) / 62608

= 688 / 728

= 688

Step2:

LCM(8, 558) = 2232

GCD(8, 558) = ( 8 x 558 ) / 2232

= 8 / 558

= 8

Step3:

LCM(2, 102) = 102

GCD(2, 102) = ( 2 x 102 ) / 102

= 2 / 102

= 2

So, Greatest Common Divisor of 688, 728, 558, 102 is 2
