What number do I multiply by to give me 1,428 outof 1,2,6, and8.
Answered by Ms. Sue
Divide 1,428 by each of those numbers. What do you get?

Answered by John
There are some short cuts:

1 will always work

since the number is even (ends in 8)
the number is divisible by 2.

If the sum of the digits is divisible by 3 then the number is divisible by 3.

If the number is divisible by 2 and 3 then it is divisible by 6.
