properties of multiples question

[jmuduke08]

I was reviewing an OG problem and in the explanation, you all mention the "properties of multiples". If possible, can anyone help me with what these properties are specifically? I am having some difficulty thinking about multiples. Thanks!

I don't know which problem you are talking about and don't know any further details but perhaps this is what you mean :

If you add or subtract a multiple of N you get a result that is a multiple of N.

That is my best guess. There is no way to search for keywords in the books that are the guides but pg 15/16 of Number Properties fourth edition mentions the above and I think this is what you may be talking about precluding any use of divination.

The problem and a paste of the explanation would have helped.

I would agree with atharshiraz; if you add or subtract a multiple of N you get a result that is a multiple of N. Also, a multiple will contain all the prime factors of the integer that the multiple is a multiple of. For example, a multiple of 36 must contain the prime factors 2,2,3,3. Also, please remember that there is an infinite number of multiples. For examples, the multiples of 36 would be 0 (0*36), 36 (1*36), 72 (2*36), 108, 144, . . .
