Given numbers are 403, 669, 297, 810

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 669 are 3 x 223

Prime factors of 297 are 3 x 3 x 3 x 11

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

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

Given numbers are 403, 669, 297, 810

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

Apply this formula for all numbers.

Step1:

LCM(403, 669) = 269607

GCD(403, 669) = ( 403 x 669 ) / 269607

= 403 / 669

= 403

Step2:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 403, 669, 297, 810 is 1
