Given numbers are 380, 255, 623

The list of prime factors of all numbers are

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 255 are 3 x 5 x 17

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 380, 255, 623

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

Apply this formula for all numbers.

Step1:

LCM(380, 255) = 19380

GCD(380, 255) = ( 380 x 255 ) / 19380

= 380 / 255

= 380

Step2:

LCM(5, 623) = 3115

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

= 5 / 623

= 5

So, Greatest Common Divisor of 380, 255, 623 is 1
