Question

Express $71$ as the sum of three odd prime numbers?

Answer 1

Prime Numbers:The numbers which have only two factors $1$ and itself are called Prime Numbers.

$$\begin{gathered} \mathrm{71=11+19+41} \\ \mathrm{Or}71=17+23+31 \end{gathered}$$

So $71$ can be expressed as sum of $11,19\mathrm{and}41$ or $17,23\mathrm{and}31$
