Given numbers are 285, 648, 911, 845

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

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

Prime factors of 911 are 911

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 285, 648, 911, 845

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

Apply this formula for all numbers.

Step1:

LCM(285, 648) = 61560

GCD(285, 648) = ( 285 x 648 ) / 61560

= 285 / 648

= 285

Step2:

LCM(3, 911) = 2733

GCD(3, 911) = ( 3 x 911 ) / 2733

= 3 / 911

= 3

Step3:

LCM(1, 845) = 845

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

= 1 / 845

= 1

So, Greatest Common Divisor of 285, 648, 911, 845 is 1
