Given numbers are 663, 391, 889, 111

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

Apply this formula for all numbers.

Step1:

LCM(663, 391) = 15249

GCD(663, 391) = ( 663 x 391 ) / 15249

= 663 / 391

= 663

Step2:

LCM(17, 889) = 15113

GCD(17, 889) = ( 17 x 889 ) / 15113

= 17 / 889

= 17

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 663, 391, 889, 111 is 1
