HOLA USER ✌

HERE'S YOUR ANSWER FRIEND,

◾◾◾◾◾◾◾◾◾◾◾◾

ITS NOT A PRIME NUMBER,

BUT ITS A COMPOSITE NUMBER.

IN THIS WAY

==>

2 X 5 X 7 X 11 X 13 + 13

==> 13[(2 X 5 X 7 X 11) + 1]

==> 13[(770) + 1]

==> 13[771]

SINCE,

THE GIVEN NUMBER HAS 13 AS ITS FACTOR,

HENCE,

IT IS A COMPOSITE NUMBER.

HOPE IT HELPS YOU.
