120150

120150 is an integer. It is even and composite. Its prime factorization is 2 × 3^3 × 5^2 × 89, which shows it is divisible by 2, 3, 5, and 89, among others. With exponents 1, 3, 2, and 1, the number has 48 positive divisors. The sum of its digits is 9, so the number is divisible by 9 and by extension by 3. It is also a Harshad number in base 10, since 120150 ÷ 9 equals 13350.

In decimal representation, 120150 ends with 0, indicating divisibility by 10 and by 50. Because its factorization contains 2 and 5^2, it is divisible by 50, 75, 150, and many multiples arising from the included primes. Its square root is approximately 346.7, so to test primality only divisors up to that bound are possible; since it has several small prime factors, it is clearly not prime.

Context: In arithmetic and number theory, 120150 is used as an example of a moderately large composite number with a nontrivial factorization. It appears in problems involving divisibility, factor counting, and Harshad numbers. As a six-digit even number, it is in the same range as many integers used in enumerative puzzles and numerical demonstrations.
