Question

Fill in the blanks.

(c) ___, $2$, ____ ,_____, _____, ______ are factors of $20$.

Answer 1

Find the factors of the given number.

Given number: $20$

As $1\times 20=20$

$$\begin{gathered} 2\times 10=20 \\ 4\times 5=20 \\ 5\times 4=20 \\ 10\times 2=20 \\ 20\times 1=20 \end{gathered}$$

So we can say, $1,2,4,5,10$ and $20$ are the factors of $20$.

Hence, $\underline{1},2,\underline{4},\underline{5},\underline{10},\underline{20}$are factors of $20$.
