Given numbers are 395, 500, 647, 845

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 647 are 647

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 395, 500, 647, 845

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

Apply this formula for all numbers.

Step1:

LCM(395, 500) = 39500

GCD(395, 500) = ( 395 x 500 ) / 39500

= 395 / 500

= 395

Step2:

LCM(5, 647) = 3235

GCD(5, 647) = ( 5 x 647 ) / 3235

= 5 / 647

= 5

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 395, 500, 647, 845 is 1
