Form Factor is the size, configuration, or physical arrangement of a computer hardware object.
The three components that must have the same form factor in a computer are the case, power supply and motherboard. The case should be able to support the form factor of the motherboard and the motherboard should be able to support the CPU socket type.
A form factor of a motherboard is it's size relative to other motherboards, some computer cases cannot support motherboards who's form factors are too small, or large for it.The form factors I can remember off the top of my head are:ATXMicro ATXMini ITXNano ITXPico ITX
Any standardized case will hold any motherboards of that form factor, such as ATX or microATX.
Actually, the CORRECT answer is that the form factor of motherboards pertains to the size and shape of the board. There is no other answer to this question.

Desktop motherboards all conform to one of several standard form factors, such as ATX, microATX, NLX, or mini-ITX. The motherboards in laptops, however, all have different sizes and are custom fitted for the laptop chassis. Laptop motherboards do not typically provide the number of expansion slots found in desktop motherboards.
