7734

7734 is a four-digit integer in base 10. It factors as 2 × 3 × 1289, making it a composite number. It is even and divisible by 3 and 6, but not by 9, since the sum of its digits is 7 + 7 + 3 + 4 = 21. The digit sum indicates divisibility by 3, while 21 is not a multiple of 9.

A notable recreational property of 7734 relates to seven-segment calculator displays. If the digits are entered on a calculator and the device is rotated 180 degrees, the number reads as the word “hELL.” The letters result from the way certain digits resemble letters when inverted: 3 becomes E, 4 becomes h, and 7 becomes L. This phenomenon is part of the broader practice of calculator spelling, used in puzzles and light humor.

In cultural contexts, 7734 is often cited as an example of how digital displays can produce words from numbers. It is frequently mentioned in discussions of calculator literacy, novelty numbers, and pop-culture trivia about upside-down text. While it has no widely recognized special status in formal number theory beyond its basic arithmetic properties, its upside-down interpretation keeps it familiar to many readers.
