This post received KUDOS

I just got a question on a practice test wrong because I didn't consider 0 (zero) to be a multiple of 5 (or any integer for that matter). So, what's the rule on the GMAT?

Do we consider 0 to be a multiple of every number?

Do we consider 0 to be a multiple of every number?

An integer \(a\) is a multiple of an integer \(b\) means that \(\frac{a}{b}=integer\): so, as 0 divided by any integer (except zero itself) yields an integer then yes, zero is a multiple of every integer (except zero itself).

Also on GMAT when we are told that \(a\) is divisible by \(b\) (or which is the same: "\(a\) is multiple of \(b\)", or "\(b\) is a factor of \(a\)"), we can say that: 1. \(a\) is an integer; 2. \(b\) is an integer; 3. \(\frac{a}{b}=integer\).

Dear Bunuel,

And the first factor of any number(>=0) is 1. am I right?

thanks Sid

Yes, the smallest factor, the smallest positive divisor of any positive integer is 1.

Hi, Then why LCM of two numbers not zero?

By definition the lowest common multiple of two integers a and b is the smallest positive integer that is a multiple both of a and of b.

Dear Bunuel, Does zero (0) consider as consecutive even integers? (0)(2)(4)(6)(8)

0 is an even integer, so it can be a part of the sequence of even numbers.
