14781546

14781546 is a natural number. It is an even, composite integer whose prime factorization is 2 × 3^2 × 13 × 181 × 349, or equivalently 2 · 3^2 · 13 · 181 · 349. This decomposition shows that the number has five distinct prime factors and a total of six prime factors counted with multiplicity.

As a consequence of its factorization, 14781546 has 48 positive divisors. The divisor count follows from the exponents in the prime factorization: (1+1)(2+1)(1+1)(1+1)(1+1) = 2·3·2·2·2 = 48. The number is not a perfect square or higher power since not all prime exponents are even.

The digit sum of 14781546 is 36, which confirms divisibility by 9 (and thus by 3 as well). It is also divisible by 2, and because 9 and 2 are factors, the number is divisible by 18. Its full set of prime factors includes 2, 3, 13, 181, and 349, indicating a diverse factor structure that illustrates basic properties of multiplicative decompositions in integers.

In mathematical contexts, 14781546 can be cited as an example of a composite with multiple distinct odd prime factors and a modest divisor count, useful for teaching concepts such as prime factorization, divisor counting, and parity. In decimal notation it is simply 14,781,546; in scientific notation it is 1.4781546 × 10^7.
