## factor,

in arithmetic, any number that divides a given number evenly, i.e., without any remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12. Similarly in algebra, any one of the algebraic expressions multiplied by another to form a product is a factor of that product, e.g., a+b and ab are factors of a2b 2, since (a+b)(ab)=a2b2. In general, if r is a rootroot,
in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function. If f is a polynomial, r is called a root of f; for example, r=3 and r
of a polynomialpolynomial,
mathematical expression which is a finite sum, each term being a constant times a product of one or more variables raised to powers. With only one variable the general form of a polynomial is a0xn+a1x
equation f(x)=0, then (xr) is a factor of the polynomial f(x).

Of note, other studies carried out within 1975-1979 timeframe yielded similar results, even though it should be pointed out that the focus of the later studies devoted to this problem had mostly been shifted from familial factors, in particular familial relations favoring drug addiction onset (Coleman & Stanton 1978; Harbin & Maziar 1975).

The deCODE project, for instance, already has isolated genes that appear to contribute to osteoporosis, stroke, diabetes, and several other complex diseases using historical and contemporary health information and DNA samples from more than 100,000 residents of Iceland (deCODE Genetics 2004), although some of those findings may turn out to be limited to rarer familial factors.
