Given numbers are 645, 845, 396, 799

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 845 are 5 x 13 x 13

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 799 are 17 x 47

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

Given numbers are 645, 845, 396, 799

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

Apply this formula for all numbers.

Step1:

LCM(645, 845) = 109005

GCD(645, 845) = ( 645 x 845 ) / 109005

= 645 / 845

= 645

Step2:

LCM(5, 396) = 1980

GCD(5, 396) = ( 5 x 396 ) / 1980

= 5 / 396

= 5

Step3:

LCM(1, 799) = 799

GCD(1, 799) = ( 1 x 799 ) / 799

= 1 / 799

= 1

So, Greatest Common Divisor of 645, 845, 396, 799 is 1
