Given numbers are 164, 447, 440, 255

The list of prime factors of all numbers are

Prime factors of 164 are 2 x 2 x 41

Prime factors of 447 are 3 x 149

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

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 164, 447, 440, 255

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

Apply this formula for all numbers.

Step1:

LCM(164, 447) = 73308

GCD(164, 447) = ( 164 x 447 ) / 73308

= 164 / 447

= 164

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 164, 447, 440, 255 is 1
