Given numbers are 866, 390, 891, 544

The list of prime factors of all numbers are

Prime factors of 866 are 2 x 433

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Given numbers are 866, 390, 891, 544

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

Apply this formula for all numbers.

Step1:

LCM(866, 390) = 168870

GCD(866, 390) = ( 866 x 390 ) / 168870

= 866 / 390

= 866

Step2:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

Step3:

LCM(1, 544) = 544

GCD(1, 544) = ( 1 x 544 ) / 544

= 1 / 544

= 1

So, Greatest Common Divisor of 866, 390, 891, 544 is 1
