Given numbers are 445, 624, 638, 508

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 638 are 2 x 11 x 29

Prime factors of 508 are 2 x 2 x 127

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

Given numbers are 445, 624, 638, 508

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

Apply this formula for all numbers.

Step1:

LCM(445, 624) = 277680

GCD(445, 624) = ( 445 x 624 ) / 277680

= 445 / 624

= 445

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 445, 624, 638, 508 is 1
