The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 817, 848, 648, 638

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

Apply this formula for all numbers.

Step1:

LCM(817, 848) = 692816

GCD(817, 848) = ( 817 x 848 ) / 692816

= 817 / 848

= 817

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 638) = 638

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

= 1 / 638

= 1

So, Greatest Common Divisor of 817, 848, 648, 638 is 1
