Problem Solving

Another odd question...
Thanks a bunch!

Hello,

No. 0 is not a multiple of 3. The reason is the basic tenet that factors and multiples are a concept pertaining to natural numbers only.

Cheers,

0 is a multiple of every number and a factor of no number.

Many questions specifically reference "positive multiples", but if they don't then negative numbers can also be multiples.

For example, the set of all multiples of 5 is:

{... -15, -10, -5, 0, 5, 10, 15, ...}

By convention, if a question asks for the lowest common multiple of two numbers, the answer will be the lowest common positive multiple.

I think 0 is a multiple of any number. consider 0xn=0

That is correct sorry, misread.

I think we can re say it like this
that
Zero is multiple of every number, But No Number is a multiple of Zero Other than Zero.
