Given that

number = 1497375

So find the prime factor of the no.

$\therefore 1497375=3\times 3\times 5\times 5\times 5\times 11\times 11\times 11$

Finding pairs of 3 in the factors

$=(5\times 5\times 5)\times (11\times 11\times 11)\times (3\times 3)$

one pair of digit 3 is incomplete in

order to make a cube

$\therefore$ Number to be multiplied = 3
