Now I’ll share some information about the number 1316:

- 1316 is a composite number.
- Prime factorization: 1316 = 2 × 2 × 7 × 47, which can be written 1316 = 2² × 7 × 47
- The exponents in the prime factorization are 2, 1, and 1. Adding one to each and multiplying we get (2 + 1)(1 + 1)(1 + 1) = 3 × 2 × 2 = 12. Therefore 1316 has exactly 12 factors.
- Factors of 1316: 1, 2, 4, 7, 14, 28, 47, 94, 188, 329, 658, 1316
- Factor pairs: 1316 = 1 × 1316, 2 × 658, 4 × 329, 7 × 188, 14 × 94, or 28 × 47
- Taking the factor pair with the largest square number factor, we get √1316 = (√4)(√329) = 2√329 ≈ 36.27671

1316 is the difference of two squares two different ways:

330² – 328² = 1316

54² – 40² = 1316
