Given numbers are 918, 620, 449, 855

The list of prime factors of all numbers are

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 449 are 449

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 918, 620, 449, 855

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

Apply this formula for all numbers.

Step1:

LCM(918, 620) = 284580

GCD(918, 620) = ( 918 x 620 ) / 284580

= 918 / 620

= 918

Step2:

LCM(2, 449) = 898

GCD(2, 449) = ( 2 x 449 ) / 898

= 2 / 449

= 2

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 918, 620, 449, 855 is 1
