Given numbers are 445, 235, 644

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 235 are 5 x 47

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 445, 235, 644

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

Apply this formula for all numbers.

Step1:

LCM(445, 235) = 20915

GCD(445, 235) = ( 445 x 235 ) / 20915

= 445 / 235

= 445

Step2:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

So, Greatest Common Divisor of 445, 235, 644 is 1
