The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 345 are 3 x 5 x 23

Prime factors of 403 are 13 x 31

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

Given numbers are 445, 345, 403

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

Apply this formula for all numbers.

Step1:

LCM(445, 345) = 30705

GCD(445, 345) = ( 445 x 345 ) / 30705

= 445 / 345

= 445

Step2:

LCM(5, 403) = 2015

GCD(5, 403) = ( 5 x 403 ) / 2015

= 5 / 403

= 5

So, Greatest Common Divisor of 445, 345, 403 is 1
