Given numbers are 689, 433, 305, 880

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

Apply this formula for all numbers.

Step1:

LCM(689, 433) = 298337

GCD(689, 433) = ( 689 x 433 ) / 298337

= 689 / 433

= 689

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 689, 433, 305, 880 is 1
