Given numbers are 689, 251, 82, 288

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

Apply this formula for all numbers.

Step1:

LCM(689, 251) = 172939

GCD(689, 251) = ( 689 x 251 ) / 172939

= 689 / 251

= 689

Step2:

LCM(1, 82) = 82

GCD(1, 82) = ( 1 x 82 ) / 82

= 1 / 82

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 689, 251, 82, 288 is 1
