Hey friend!!

Here's ur answer...

=====================

$3 \times 5 \times 7 + 7 \\ = 7(3 \times 5 \times 1 + 1) \\ = 7(15 + 1) \\ = 7 \times 16 . \\ \\ we \: know \: that \: \\ composite \: numbers \: have \: more \: \\ than \: 2 \: factors. \\ \\ here \: \\ the \: given \: number \: also \: shows \: the \: same \: \\ property. \\ \\ so \: the \: given \: number \: is \: composite.$
