A multiplying factor or product of group of multiplicative factors in terms of letters in an algebraic term is called a literal coefficient.

$(1)$ $\,\,\, 7a$

$a$ is a letter and a multiplicative factor in the term $7a$. Therefore, the letter $a$ is called as a literal coefficient of $7$ in alternative term $7a$.

$(2)$ $\,\,\, 2xy$

In the term $2xy$,

- $x$ is letter and a multiplying factor. So, $x$ is called as literal coefficient of $2y$.
- $y$ is also a letter and another multiplicative factor. Therefore, $y$ is called as a literal coefficient of $2x$.
- $xy$ is a product of group of multiplicative factors. Hence, $xy$ is called as a literal coefficient of $2$.

$(3)$ $\,\,\, -p^{\displaystyle 2}qr$

The algebraic term $-p^{\displaystyle 2}qr$ is $-1p^{\displaystyle 2}qr$. In this term,

- $p^{\displaystyle 2}$ is the literal coefficient of $-qr$
- $p^{\displaystyle 2}q$ is the literal coefficient of $–r$
- $p^{\displaystyle 2}r$ is the literal coefficient of $–q$
- $p^{\displaystyle 2}qr$ is the literal coefficient of $-1$
- $p$ is the literal coefficient of $-pqr$
- $pq$ is the literal coefficient of $-pr$
- $pr$ is the literal coefficient of $-pq$
- $pqr$ is the literal coefficient of $-p$
- $q$ is the literal coefficient of $-p^{\displaystyle 2}r$
- $qr$ is the literal coefficient of $-p^{\displaystyle 2}$
- $r$ is the literal coefficient of $-p^{\displaystyle 2}q$
