7922

7922 is a natural number that follows 7921 and precedes 7923. It is even and composite, with prime factorization 2 × 17 × 233. The odd prime factors are both congruent to 1 modulo 4, which implies that 7922 can be expressed as a sum of two squares; for example, 7922 = 41^2 + 79^2. The digit sum of 7922 is 7 + 9 + 2 + 2 = 20, so it is not divisible by 3 or 9.

In base 2, 7922 is represented as 1111011110010. The number is congruent to 2 modulo 4 (and also modulo 8), since 7922 ≡ 2 (mod 4) and 7922 ≡ 2 (mod 8). It is not a prime, not a perfect square, and it is not a triangular number.

From a mathematical perspective, 7922 serves as an example of a number with a factorization into three primes where the two odd primes are each 1 mod 4, reinforcing the general theorem that such numbers admit representations as a sum of two squares. Beyond its arithmetic properties, 7922 does not have a widely recognized significance in standard mathematical sequences or notable classifications, and it typically appears only as a specific value within broader numerical discussions or cataloging.
