Given numbers are 663, 680, 687, 793

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

Apply this formula for all numbers.

Step1:

LCM(663, 680) = 26520

GCD(663, 680) = ( 663 x 680 ) / 26520

= 663 / 680

= 663

Step2:

LCM(17, 687) = 11679

GCD(17, 687) = ( 17 x 687 ) / 11679

= 17 / 687

= 17

Step3:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

So, Greatest Common Divisor of 663, 680, 687, 793 is 1
