Given numbers are 440, 580, 485, 623

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 580 are 2 x 2 x 5 x 29

Prime factors of 485 are 5 x 97

Prime factors of 623 are 7 x 89

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

Given numbers are 440, 580, 485, 623

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

Apply this formula for all numbers.

Step1:

LCM(440, 580) = 12760

GCD(440, 580) = ( 440 x 580 ) / 12760

= 440 / 580

= 440

Step2:

LCM(20, 485) = 1940

GCD(20, 485) = ( 20 x 485 ) / 1940

= 20 / 485

= 20

Step3:

LCM(5, 623) = 3115

GCD(5, 623) = ( 5 x 623 ) / 3115

= 5 / 623

= 5

So, Greatest Common Divisor of 440, 580, 485, 623 is 1
