Given numbers are 663, 891, 905, 800

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 905 are 5 x 181

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 663, 891, 905, 800

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

Apply this formula for all numbers.

Step1:

LCM(663, 891) = 196911

GCD(663, 891) = ( 663 x 891 ) / 196911

= 663 / 891

= 663

Step2:

LCM(3, 905) = 2715

GCD(3, 905) = ( 3 x 905 ) / 2715

= 3 / 905

= 3

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 663, 891, 905, 800 is 1
