#5*3*3*3#

Explanation:

If #135# is divided by #5# then the answer will be #27#, so #135# can be written as #5*color(red)27#

#color(red)27# is the same as #color(red)(9*3)#, so #5*color(red)27# can be written as #5*color(red)(color(green)9*3)#

#color(green)9# is the same as #color(green)(3*3)# so #5*color(green)9*3# can be written as #5*color(green)(3*3)*3#

The final answer is #5*3*3*3# because it can't be broken down more (they all are prime numbers) and this is called prime factorization
