12690447

12690447 is a positive integer. In decimal notation it is written as 12,690,447, and it lies in the range of tens of millions (between 10,000,000 and 99,999,999). The sum of its digits is 33, which makes the number divisible by 3. The last digit is 7, so it is not divisible by 2 or 5, and it is not even.

Prime factorization: 12690447 = 3 × 7 × 11 × 137 × 401. All factors are distinct, so the number is square-free. Consequently, it has 2^5 = 32 positive divisors.

Because its prime factors are distinct, 12,690,447 is not a prime, nor a perfect power. The factorization also implies it is not a palindrome in base-10, and its representation in other bases would require computation.

The number is an example of a large composite integer that factors into small primes and a couple of mid-sized primes (137 and 401). In mathematical contexts, such factorizations illustrate how a number can be built from several relatively small prime components, yielding a product that grows quickly while remaining composed of simple factors.
