98765432

98765432 is an even integer with eight digits. Its decimal representation uses the digits 9 through 2 in strictly descending order, forming a simple example of a digit permutation that excludes 1 and 0.

Numerically, 98,765,432 equals 2^3 times 12,345,679. The factor 12,345,679 further factors as 37 times 333,667 (since 12,345,679 = 37 × 333,667). Therefore the prime factorization of 98,765,432 is 2^3 × 37 × 333,667. The number is divisible by 2, 4, and 8, but not by 3 or 9, as the digit sum is 44. An interesting property is that 12,345,679 × 9 equals 111,111,111, which relates to certain repeating decimals in base-10 expansions.

Because its digits form a descending sequence from 9 to 2, 98765432 is sometimes cited in puzzles and demonstrations of digit manipulation. It does not have special mathematical significance beyond being a concrete, non-repeating eight-digit example with unique digits. In various contexts it may be used as a test value in software, number theory examples, or educational materials illustrating factors, divisibility, and decimal representation.
