Now let me tell you a little about the number 942:

It is the sum of four consecutive prime numbers:

229 + 233 + 239 + 241 = 942

It is the hypotenuse of a Pythagorean triple:

510-792-942 which is **6** times (85-132-**157**)

942 is a palindrome in two other bases and a repdigit in another:

787 in BASE 11, because 7(11²) + 8(11¹) + 7(11⁰) = 942

272 in BASE 20, because 2(20²) + 7(20¹) + 2(20⁰) = 942

666 in BASE 12, because 6(12²) + 6(12¹) + 6(12⁰) = 6(144+12+1) = 6(157) = 942

942³ is **8**35,**8**96,**888**. Stetson.edu tells us that 942³ is the smallest perfect cube that contains five **8**‘s.

- 942 is a composite number.
- Prime factorization: 942 = 2 × 3 × 157
- 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 942 has exactly 8 factors.
- Factors of 942: 1, 2, 3, 6, 157, 314, 471, 942
- Factor pairs: 942 = 1 × 942, 2 × 471, 3 × 314, or 6 × 157
- 942 has no square factors that allow its square root to be simplified. √942 ≈ 30.6920185
