Given numbers are 638, 731, 506, 445

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 731 are 17 x 43

Prime factors of 506 are 2 x 11 x 23

Prime factors of 445 are 5 x 89

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

Given numbers are 638, 731, 506, 445

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

Apply this formula for all numbers.

Step1:

LCM(638, 731) = 466378

GCD(638, 731) = ( 638 x 731 ) / 466378

= 638 / 731

= 638

Step2:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 638, 731, 506, 445 is 1
