Given numbers are 689, 395, 850, 863

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

Apply this formula for all numbers.

Step1:

LCM(689, 395) = 272155

GCD(689, 395) = ( 689 x 395 ) / 272155

= 689 / 395

= 689

Step2:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 689, 395, 850, 863 is 1
