Given numbers are 638, 805, 732, 448

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 805 are 5 x 7 x 23

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

Given numbers are 638, 805, 732, 448

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

Apply this formula for all numbers.

Step1:

LCM(638, 805) = 513590

GCD(638, 805) = ( 638 x 805 ) / 513590

= 638 / 805

= 638

Step2:

LCM(1, 732) = 732

GCD(1, 732) = ( 1 x 732 ) / 732

= 1 / 732

= 1

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 638, 805, 732, 448 is 1
