GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 494) = 169936
GCD(688, 494) = ( 688 x 494 ) / 169936
= 688 / 494
= 688
Step2:
LCM(2, 870) = 870
GCD(2, 870) = ( 2 x 870 ) / 870
= 2 / 870
= 2
Step3:
LCM(2, 290) = 290
GCD(2, 290) = ( 2 x 290 ) / 290
= 2 / 290
= 2
So, Greatest Common Divisor of 688, 494, 870, 290 is 2
