## Common factor

An element of return that influences many assets. According to multiple factor risk models, the factors determine correlations between asset returns. Common factors include size (often measured by market capitalization), valuation measures such as price to book value ratio and dividend yield, industries and risk indices.

Note that because the [[alpha].sub.i] have greatest common divisor 1, we have [zeta] = 1 as a pole of order N + 1, and the other poles have order strictly less.
An element b in CD(B) is a greatest common divisor of B if and only if CD(B) = D(b).
Theorem 7 Consider n +1 unscaled pots with volumes [a.sub.1], [a.sub.2], ..., [a.sub.n] and [a.sub.n+1], where [a.sub.1], [a.sub.2], ..., [a.sub.n], [a.sub.n+1] [member of] [N.sup.*] and denote by d the greatest common divisor of [a.sub.1], [a.sub.2], ..., [a.sub.n].
