Given numbers are 440, 255, 608, 861

The list of prime factors of all numbers are

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

Prime factors of 255 are 3 x 5 x 17

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 440, 255, 608, 861

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

Apply this formula for all numbers.

Step1:

LCM(440, 255) = 22440

GCD(440, 255) = ( 440 x 255 ) / 22440

= 440 / 255

= 440

Step2:

LCM(5, 608) = 3040

GCD(5, 608) = ( 5 x 608 ) / 3040

= 5 / 608

= 5

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 440, 255, 608, 861 is 1
