Given numbers are 688, 390, 704, 626

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

Apply this formula for all numbers.

Step1:

LCM(688, 390) = 134160

GCD(688, 390) = ( 688 x 390 ) / 134160

= 688 / 390

= 688

Step2:

LCM(2, 704) = 704

GCD(2, 704) = ( 2 x 704 ) / 704

= 2 / 704

= 2

Step3:

LCM(2, 626) = 626

GCD(2, 626) = ( 2 x 626 ) / 626

= 2 / 626

= 2

So, Greatest Common Divisor of 688, 390, 704, 626 is 2
