Given numbers are 403, 440, 261, 904

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 261 are 3 x 3 x 29

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 403, 440, 261, 904

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

Apply this formula for all numbers.

Step1:

LCM(403, 440) = 177320

GCD(403, 440) = ( 403 x 440 ) / 177320

= 403 / 440

= 403

Step2:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 403, 440, 261, 904 is 1
