Given numbers are 689, 867, 799, 686

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

Apply this formula for all numbers.

Step1:

LCM(689, 867) = 597363

GCD(689, 867) = ( 689 x 867 ) / 597363

= 689 / 867

= 689

Step2:

LCM(1, 799) = 799

GCD(1, 799) = ( 1 x 799 ) / 799

= 1 / 799

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 689, 867, 799, 686 is 1
