Given numbers are 645, 445, 737, 345

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 445 are 5 x 89

Prime factors of 737 are 11 x 67

Prime factors of 345 are 3 x 5 x 23

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

Given numbers are 645, 445, 737, 345

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

Apply this formula for all numbers.

Step1:

LCM(645, 445) = 57405

GCD(645, 445) = ( 645 x 445 ) / 57405

= 645 / 445

= 645

Step2:

LCM(5, 737) = 3685

GCD(5, 737) = ( 5 x 737 ) / 3685

= 5 / 737

= 5

Step3:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

So, Greatest Common Divisor of 645, 445, 737, 345 is 1
