7426

7426 is a natural number that follows 7425 and precedes 7427. In mathematics, it is even and composite, with prime factorization 2 × 47 × 79. As a product of three distinct primes, it is square-free and has eight positive divisors: 1, 2, 47, 79, 94, 158, 3713, and 7426. The sum of its digits is 19; thus it is not divisible by 3 or 9, and it is congruent to 1 modulo 9. It is not expressible as a sum of two squares, since both 47 and 79 are congruent to 3 mod 4 and occur with odd exponent in the factorization.

In other bases or numeral systems, 7426 would have different representations, but its arithmetic properties remain the same. The number is used in practical contexts as an identifier: it may appear as a model number, catalog number, or serial designation in lists and inventories, independent of any particular significance beyond its numerical value. It does not, by itself, denote a widely known mathematical constant or widely cited historical event.
