If X is a positive integer and (405)

is a multiple of 3

, what is the largest possible value of X?

X -

- A. 5.
- B. 12.
- C. 16.
- D. 20
- E. 26.

Find the factors of (405)

and see what the largest value of X can be.

405 = 81 ֳ— 5 = 9 ֳ— 9 ֳ— 5 = 3 ֳ— 3 ֳ— 3 ֳ— 3 ֳ— 5

(405)

= (3 ֳ— 3 ֳ— 3 ֳ— 3 ֳ— 5)

ֳ— 5

.

The largest possible value of 3 -

that is still a factor of (405)

is the largest possible value of X and that is 3

.

X -

X = 16.
