Question

Write all the composite numbers between $1$ to $100$.

Answer 1

A composite number is a natural number that has more than two factors.

Now, composite numbers between $1$ to $100$ are:

$$\begin{gathered} 4,6,8,9,10,12,14,15,16,18,20 \\ 21,22,24,25,26,27,28,30 \\ 32,33,34,35,36,38,39,40 \\ 42,44,45,46,48,49,50 \\ 51,52,54,55,56,57,58,60 \\ 62,63,64,65,66,68,69,70 \\ 72,74,75,76,77,78,80 \\ 81,82,84,85,86,87,88,90 \\ 91,92,93,94,95,96,98,99,100 \end{gathered}$$
