Given numbers are 663, 930, 931, 168

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 931 are 7 x 7 x 19

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 663, 930, 931, 168

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

Apply this formula for all numbers.

Step1:

LCM(663, 930) = 205530

GCD(663, 930) = ( 663 x 930 ) / 205530

= 663 / 930

= 663

Step2:

LCM(3, 931) = 2793

GCD(3, 931) = ( 3 x 931 ) / 2793

= 3 / 931

= 3

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 663, 930, 931, 168 is 1
