Everything you need to know about ‘0’ for GMAT
\(0\) is an integer.
\(0\) is an even integer.
\(0\) is not Prime Number.
\(0\) is not a natural number.
\(0\) is the only number that is neither positive nor negative.
\(0\) is the only number that is equal to its opposite; \(0=-0\).
\(0\) is multiple of every integer; \(0*2=0\)
\(0\) is the FIRST multiple of any number but NOT the FIRST POSITIVE multiple.
\(0\) is not a factor of any integer EXCEPT \(0\). OG 208
\(\frac{a}{0}=\) meaningless,undefined
\(\frac{0}{0}=\) indeterminate
\(\frac{0}{a}=0\)
\(0\) is a perfect square and also perfect cube.
\(0\) is the only number that when raised to the zero power does not necessarily equal to 1; \(0^0≠1\).
\(0^0\) is indeterminate and never appear on the GMAT
\(0^n=0 (n\neq{0})\)
\(n^0=1 (n\neq{0})\)
\(0^0≠1\)
\(0!=1\)

is zero a factor of zero?

@Mahmud6, "Please recheck your statement that zero is not a factor of any number except zero".
Zero is not a factor of anything, period. Look at it this way: for y to be a factor of x, you would check whether x/y = integer.
For example, 3 is a factor of 15 because 15/3 = 5, an integer. But n/0 = undefined, not an integer. Thus zero cannot be a factor of n, regardless of n's value. You cannot say that 0/0 = 0 just because zero is the numerator. The denominator of 0 makes 0/0 undefined.
