Given numbers are 689, 403, 824

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

Apply this formula for all numbers.

Step1:

LCM(689, 403) = 21359

GCD(689, 403) = ( 689 x 403 ) / 21359

= 689 / 403

= 689

Step2:

LCM(13, 824) = 10712

GCD(13, 824) = ( 13 x 824 ) / 10712

= 13 / 824

= 13

So, Greatest Common Divisor of 689, 403, 824 is 1
