What can I tell you about the number 1030?

It’s the sum of two consecutive prime numbers:
509 + 521 = 1030

It’s the hypotenuse of a Pythagorean triple:
618-824-1030 which is (3-4-5) times 206

It’s palindrome 1102011 in BASE 3 because 3⁶ + 3⁵ + 2(3³) + 3¹ + 3⁰ = 1030

  • 1030 is a composite number.
  • Prime factorization: 1030 = 2 × 5 × 103
  • The exponents in the prime factorization are 1, 1, and 1. Adding one to each and multiplying we get (1 + 1)(1 + 1)(1 + 1) = 2 × 2 × 2 = 8. Therefore 1030 has exactly 8 factors.
  • Factors of 1030: 1, 2, 5, 10, 103, 206, 515, 1030
  • Factor pairs: 1030 = 1 × 1030, 2 × 515, 5 × 206, or 10 × 103
  • 1030 has no square factors that allow its square root to be simplified. √1030 ≈ 32.09361
