The Motorola 68040 is a microprocessor from Motorola.
It is the successor to the Motorola 68030 and is followed by the Motorola 68060 (the 68050 was an abandoned project and never shipped, the 050 was to the 040 what the 030 was to the 020, a simple die shrink and cache size increase).
Motorola's 68882 external FPU was known as a very high performance unit and Motorola did not wish to risk integrators using the "LC" version with a 68882 rather than the more profitable full "RC" unit.

Successor to the Motorola 68030 and followed by the 68060 - not 68050.
The 68050 would have been a 68040 with some bugs fixed, which didn't really warrant a new name so it was sold as a 68040.
The 68LC040 is a 68040 without a built-in math coprocessor (FPU), the 68EC040 a 68040 without a memory manager or built-in FPU.

 68k information - Search.com
The Motorola 680x0/0x0/m68k/68k/68K family of CISC microprocessor CPU chips were 32-bit from the start, and were the primary competition for the Intel x86 family of chips.
There is also no revision of the 68060, as Motorola was in the process of shifting away from the 68k and 88k processor lines into its new PowerPC business, so the 68070 was never developed.
Had Motorola decided to stick with the 680x0 series, it is very likely that the next processor (68080) would have resembled Intel's P6 architecture.

The newest member of the 68000 family, the 68040, essentially combines a beefed-up 68030 and the low-level functions of the 68881 floating-point coprocessor onto the same chip.
Motorola's goal appears to be to make the 68040 as suitable as possible for large-scale multiprocessing systems.
On the 68040, the only floating-point operations supported are absolute value, add, branch on condition, compare, decrement and branch conditionally, divide, move, move multiple, multiply, negate, nop, restore internal state, save internal state, set on condition, square root, subtract, trap on condition, and test.

Due to the fact that R and D costs for the evolution of the 68040 have been very low (reports suggest that a team of as few as three engineers have been involved in the continuing work), the current 1.9 GHz model costs approximately $19 in lots of 100.
Apple could use the 68040, a 4 GB hard drive, 32 MB of RAM, a 15" CRT (with the headlong rush into flat-panel LCD technology, they are practically giving away CRT's these days), and a standard CD-ROM to manufacture a true entry-level iMac at a cost of around $140.
