Here is some information about the number 1102:

• 1102 is a composite number.
• Prime factorization: 1102 = 2 × 19 × 29
• 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 1102 has exactly 8 factors.
• Factors of 1102: 1, 2, 19, 29, 38, 58, 551, 1102
• Factor pairs: 1102 = 1 × 1102, 2 × 551, 19 × 58, or 29 × 38
• 1102 has no square factors that allow its square root to be simplified. √1102 ≈ 33.19639

1102 = 2(29)(19) so we know that 480-1102-1202 is a Pythagorean triple
calculated from 29²-19², 2(29)(19), 29²+19²

1102 is also the hypotenuse of a Pythagorean triple:
760-798-1102 which is (20-21-29) times 38.

1102 is a palindrome when it is written in a couple of other bases:
It’s 2F2 in BASE 20 (F is 15 base 10) because 2(20²) + 15(20) + 2(1) = 1102,
and it’s 262 in BASE 22 because 2(22²) + 6(22) + 2(1) = 1102.
