Given numbers are 173, 390, 602, 689

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

Apply this formula for all numbers.

Step1:

LCM(173, 390) = 67470

GCD(173, 390) = ( 173 x 390 ) / 67470

= 173 / 390

= 173

Step2:

LCM(1, 602) = 602

GCD(1, 602) = ( 1 x 602 ) / 602

= 1 / 602

= 1

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 173, 390, 602, 689 is 1
