Given numbers are 688, 508, 886, 639

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

Apply this formula for all numbers.

Step1:

LCM(688, 508) = 87376

GCD(688, 508) = ( 688 x 508 ) / 87376

= 688 / 508

= 688

Step2:

LCM(4, 886) = 1772

GCD(4, 886) = ( 4 x 886 ) / 1772

= 4 / 886

= 4

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 688, 508, 886, 639 is 1
