7678

7678 is a natural number that follows 7677 and precedes 7679. In mathematics, it is an even composite number with prime factorization 7678 = 2 × 11 × 349, a product of three distinct primes. This makes 7678 squarefree and gives it exactly eight positive divisors: 1, 2, 11, 22, 349, 698, 3839, and 7678. Consequently, 7678 is a 3-almost prime (the product of three primes, counting multiplicity).

As a result of its divisors, the sum of its proper divisors is 4922, which is less

In summary, 7678 is a squarefree, even, deficient number with exactly eight divisors, and it is the
