144153

144153 is a natural number that follows 144,152 and precedes 144,154. In mathematics, it is a composite, odd integer with a prime factorization of 3^3 × 19 × 281. This means 144153 is divisible by 3, 9, 19 and 281, and by any product of these factors.

Because the digit sum equals 18, the number is divisible by 9 (since 1+4+4+1+5+3 = 18). It is not a perfect square or cube. Its magnitude places it in the hundreds of thousands range.

Sum of divisors: the divisors arise from the prime factors 3^a with a = 0–3, together with 19 and 281. The sum of all divisors is (1+3+9+27) × (1+19) × (1+281) = 40 × 20 × 282 = 225,600. Therefore the sum of proper divisors is 225,600 − 144,153 = 81,447, which is less than 144,153. Hence 144153 is a deficient number.

Additional notes: the prime factorization shows 144153 is not prime and is not a palindrome in decimal. The component 281 is itself a prime number, and 144153 is not a Harshad number in base 10, since it is divisible by 9 but not by the digit sum 18.
