Given numbers are 689, 624, 399, 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, 624) = 33072

GCD(689, 624) = ( 689 x 624 ) / 33072

= 689 / 624

= 689

Step2:

LCM(13, 399) = 5187

GCD(13, 399) = ( 13 x 399 ) / 5187

= 13 / 399

= 13

Step3:

LCM(1, 863) = 863

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

= 1 / 863

= 1

So, Greatest Common Divisor of 689, 624, 399, 863 is 1
