Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Step-by-step explanation:

we can write this number as:--

$= 5 + 1 \times 2 \times 3 \times 4 \times 5$

just inverted it....

_______________________________

now,

$= 5(1 + 1 \times 2 \times 3 \times 4 \times 5)$

$now.. \: let \: (1 + 1 \times 2 \times 3 \times 4) = n$

$= 5n$

_______________________________

NOW, THERE 5n is divisible BY MORE THEN ONE NUMBER IT IS DIVISIBLE BY 1 AND 5 SO IT IS A COMPOSITE NUMBER.....
