Given numbers are 810, 825, 694, 403

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 694 are 2 x 347

Prime factors of 403 are 13 x 31

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

Given numbers are 810, 825, 694, 403

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

Apply this formula for all numbers.

Step1:

LCM(810, 825) = 44550

GCD(810, 825) = ( 810 x 825 ) / 44550

= 810 / 825

= 810

Step2:

LCM(15, 694) = 10410

GCD(15, 694) = ( 15 x 694 ) / 10410

= 15 / 694

= 15

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 810, 825, 694, 403 is 1
