Given numbers are 689, 617, 805, 754

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

Apply this formula for all numbers.

Step1:

LCM(689, 617) = 425113

GCD(689, 617) = ( 689 x 617 ) / 425113

= 689 / 617

= 689

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 754) = 754

GCD(1, 754) = ( 1 x 754 ) / 754

= 1 / 754

= 1

So, Greatest Common Divisor of 689, 617, 805, 754 is 1
