6 divides 54 exactly to yield 9. Then 6 and 9 are factors of 54.
It is 36.
Any number of the form a*b^4 where a and b are different prime numbers, or c^9 where c is a prime, will have exactly 10 factors.
How about 99 whose factors are: 1, 3, 9, 11 33 and 99
36 has 9 factors.
3*5*7*9 = 945 ...check if any number less than that has exactly four distinct factors.

9 The three factors are 1, 3, and 9. 9 The three factors are 1, 3, and 9.
It is 36.
Any number of the form a*b^4 where a and b are different prime numbers, or c^9 where c is a prime, will have exactly 10 factors.
Any composite number. Examples: 4 and 9 . . . (three factors) 6, 8, and 10 . . . (four factors) 12 . . . (six factors) 60 . . . (twelve factors)
4, 9, 25
Numbers with three factors are squares of primes: 4, 9, 25
