45 (forty-five) is the natural number following 44 (number), 44 and preceding 46 (number), 46. In mathematics Forty-five is the smallest Parity (mathematics), odd number that has more divisors than n+1, and that has a larger sum of divisors than n+1. It is the sixth positive integer with a ''square-prime'' prime factorization of the form p^q, with p and q Prime number, prime. 45 has an aliquot sum of 33 (number), 33 that is part of an aliquot sequence composed of five composite numbers (45, 33, 15 (number), 15, 9 (number), 9, 4 (number), 4, 3 (number), 3, 1 (number), 1, and 0), all of which are rooted in the 3-aliquot tree. This is the longest aliquot sequence for an odd number up to 45. Forty-five is the summation, sum of all single-digit decimal digits: 0+1+2+3+4+5+6+7+8+9=45. It is, equivalently, the ninth triangle number. Forty-five is also the fourth hexagonal number and the second polygonal number, hexadecagonal number, or 16-gonal number.
