What are the Factors of 4?

$4 \div 1$

$=\,\,$ $\dfrac{4}{1}$

Use the long division method to divide the number $2$ by $1$ and it helps us to know about the remainder.

$\require{enclose}
\begin{array}{rll}
4 && \hbox{} \\[-3pt]
1 \enclose{longdiv}{4}\kern-.2ex \\[-3pt]
\underline{-~~~4} && \longrightarrow && \hbox{$1 \times 4 = 4$} \\[-3pt]
\phantom{00} 0 && \longrightarrow && \hbox{No Remainder}
\end{array}$

$4 \div 2$

$=\,\,$ $\dfrac{4}{2}$

Let’s use long division method one more time to know whether the number $2$ divides itself completely or not.

$\require{enclose}
\begin{array}{rll}
2 && \hbox{} \\[-3pt]
2 \enclose{longdiv}{4}\kern-.2ex \\[-3pt]
\underline{-~~~4} && \longrightarrow && \hbox{$2 \times 2 = 4$} \\[-3pt]
\phantom{00} 0 && \longrightarrow && \hbox{No Remainder}
\end{array}$

$4 \div 3$

$=\,\,$ $\dfrac{4}{3}$

Let’s use long division method one more time to know whether the number $2$ divides itself completely or not.

$\require{enclose}
\begin{array}{rll}
1 && \hbox{} \\[-3pt]
3 \enclose{longdiv}{4}\kern-.2ex \\[-3pt]
\underline{-~~~3} && \longrightarrow && \hbox{$3 \times 1 = 3$} \\[-3pt]
\phantom{00} 1 && \longrightarrow && \hbox{Remainder}
\end{array}$

$4 \div 4$

$=\,\,$ $\dfrac{4}{4}$

Let’s use long division method one more time to know whether the number $2$ divides itself completely or not.

$\require{enclose}
\begin{array}{rll}
1 && \hbox{} \\[-3pt]
4 \enclose{longdiv}{4}\kern-.2ex \\[-3pt]
\underline{-~~~4} && \longrightarrow && \hbox{$4 \times 1 = 4$} \\[-3pt]
\phantom{00} 0 && \longrightarrow && \hbox{No Remainder}
\end{array}$
