Thank you, OEIS.org for alerting me to that very cool fact. It deserves a celebration so I made the graphic above.
Here’s more about the number 1375:
- 1375 is a composite number.
- Prime factorization: 1375 = 5 × 5 × 5 × 11, which can be written 1375 = 5³ × 11
- 1375 has at least one exponent greater than 1 in its prime factorization so √1375 can be simplified. Taking the factor pair from the factor pair table below with the largest square number factor, we get √1375 = (√25)(√55) = 5√55
- The exponents in the prime factorization are 3 and 1. Adding one to each exponent and multiplying we get (3 + 1)(1 + 1) = 4 × 2 = 8. Therefore 1375 has exactly 8 factors.
