132

132 is the natural number that comes after 131 and before 133. In mathematics, its prime factorization is 2^2 × 3 × 11, so it is a composite and even number. It has 12 positive divisors, including 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, and 132. The sum of its proper divisors is 204, which makes 132 an abundant number. The digits sum to 6, so 132 is a Harshad (Niven) number, since 132 ÷ 6 = 22. In other base representations, 132 is 10000100 in binary, 204 in octal, and 0x84 in hexadecimal. In Roman numerals it is written CXXXII.

132 is also a practical number, meaning every smaller positive integer can be expressed as a sum of distinct divisors of 132, a property that places it in a well-studied class of numbers.

In history, the year 132 CE is notable for the start of the Bar Kokhba revolt in the Roman province of Judea, led by Simon bar Kokhba; the revolt lasted until 136 CE and contributed to Roman administrative changes in the region.

Beyond mathematics and history, 132 appears as a decimal value in various measurement and coding systems (for example, hex 84, binary 10000100).
