Given numbers are 688, 392, 703, 139

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

Apply this formula for all numbers.

Step1:

LCM(688, 392) = 33712

GCD(688, 392) = ( 688 x 392 ) / 33712

= 688 / 392

= 688

Step2:

LCM(8, 703) = 5624

GCD(8, 703) = ( 8 x 703 ) / 5624

= 8 / 703

= 8

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 688, 392, 703, 139 is 1
