1259921

1259921 is a positive integer that appears in arithmetic and number theory as a concrete numerical example. It does not denote a widely recognized constant, year, or cataloged object, but like many integers it has properties that can be explored using standard tests such as divisibility, factorization, and comparisons with nearby powers.

It is an odd number and is divisible by 13, with a cofactor of 96,917, since 13 × 96,917 = 1259921. Consequently, 1259921 is not a prime. It is not a perfect square, as the nearest squares are 1122^2 = 1,258,884 and 1123^2 = 1,261,129. It is not a perfect cube either: 108^3 = 1,259,712 and 109^3 = 1,295,029 bracket the value. Thus the cube root lies between 108 and 109.

Beyond its basic arithmetic properties, 1259921 has no widely noted historical, scientific, or cultural significance. It can be referenced in discussions of factorization or in demonstrations of how small primes compose larger composite numbers. As a semiprime candidate, its factorization into 13 and 96,917 illustrates how composite numbers can be built from a small prime and a larger cofactor.
