A coefficient in literal form in an algebraic term is called a literal coefficient. In mathematics, a coefficient is basically a multiplicative factor in a term but in algebra, a literal coefficient is a multiplying factor which contains one or product of more literal numbers in an algebraic term. Examples $(1) \,\,\,\,\,$ $7a$
A leading coefficient is the coefficient of a term with the highest degree, or largest exponent, within an equation. For example, the degree of the equation 6y^4 + 5y^2 - 2y + 1 is 4, because that is the largest exponent. Therefore, the leading coefficient is 6.
