2147483645

2147483645 is a positive integer. It is equal to 2^31 − 3, and thus lies just below the maximum value of a 32-bit signed integer, which is 2^31 − 1 = 2147483647.

It factors as 2147483645 = 5 × 429,496,729, so it is composite. The cofactor 429,496,729 is odd and not divisible by 3 or 5, but further factorization (if any) is not shown here.

In hexadecimal the 32-bit representation is 0x7FFFFFFD, and in binary it is 01111111 11111111 11111111 11111101. This places the number firmly in the positive range of signed 32-bit integers.

As a Unix timestamp, 2147483645 corresponds to 2038-01-19 03:14:05 UTC, which is two seconds before the well-known 2038 problem boundary at 2147483647 (2038-01-19 03:14:07 UTC). This proximity illustrates why the 32-bit time_t limit is a notable design consideration in legacy systems.
