The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 575 are 5 x 5 x 23

Prime factors of 437 are 19 x 23

Prime factors of 441 are 3 x 3 x 7 x 7

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

Given numbers are 645, 575, 437, 441

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

Apply this formula for all numbers.

Step1:

LCM(645, 575) = 74175

GCD(645, 575) = ( 645 x 575 ) / 74175

= 645 / 575

= 645

Step2:

LCM(5, 437) = 2185

GCD(5, 437) = ( 5 x 437 ) / 2185

= 5 / 437

= 5

Step3:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

So, Greatest Common Divisor of 645, 575, 437, 441 is 1
