Given numbers are 688, 609, 319, 784

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

Apply this formula for all numbers.

Step1:

LCM(688, 609) = 418992

GCD(688, 609) = ( 688 x 609 ) / 418992

= 688 / 609

= 688

Step2:

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

= 1 / 319

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 688, 609, 319, 784 is 1
