Aug 04, 2006 · Just as “increased by a factor of 2” means “twice as large,” so does “greater by a factor of 2.” And “decreased by a factor of 2” and “less by a factor of 2” both mean “half as much” (divided by 2). I can’t think of a context in which that would not be true — but English is flexible enough that I probably shouldn’t guarantee anything!

May 19, 2012 · “by a factor of ” is used commonly to mean the same as “multiplied by” or “divided by.” If x is INCREASED by a factor of 4, it becomes 4x. If x is DECREASED by a factor of 4, it becomes x/4. The key word is the direction of change i.e. (increased / decreased) by a factor of.

“Factor” is a key word that indicates that either multiplication or division are involved. If you increase “x” by a factor of 10, then you are talking about x*10. If you decrease “x” by a factor of 10, then you are talking about x/10.

Typically, the dilution factor remains constant for each dilution, resulting in an exponential decrease in concentration. For example, a ten-fold serial dilution could result in the following concentrations: 1 M, 0.1 M, 0.01 M, 0.001 M, and so on. As is evidenced in this example, the concentration is reduced by a factor of ten in each step. [emphasis mine]

1 Answer. If the meaning is that one should divide by the factor, such that the result was the original quantity, then the usage was correct. However, if the meaning is that the result is reduced by multiplying by a factor (perhaps an arbitrary one between one and zero) then the usage was incorrect.

One of the reasons the decreased by usage is bad, is that it’s used to mean what it shouldn’t. If you say decreased by a factor of 4, then what factor of 4 are you talking about – 1, 2, 4? B is not decreased by a factor of the decrease, the factor you’re talking about has to be a factor of B!

Full Answer. The inverse relationship between the force of gravity and the distance between two objects is based on the square of that distance. This means that if the distance is doubled, the gravitational force is decreased by a factor of 4. This is because the square of 2 is 2 x 2, which equals 4.
