# Does "by a factor of more than 10" mean "10 times more"?

Context:

to overreliance on herbicides and, in particular, on glyphosate. In
the United States, glyphosate use has increased by a factor of more
than 250 - from 0.4 million kg in 1974 to 113 million kg in
2014. Global use has increased by a factor of more than 10. Not
surprisingly, glyphosate-resistant weeds have emerged and are
found today on nearly 100 million acres in 36 states. Fields must
be now be treated with multiple herbicides, including 2,4-D, a com-
ponent of the Agent Orange defoliant used in the Vietnam War.

@oristarA,

in this case it's a mathematical term --

"a number or quantity that when multiplied with another produces a given number or expression"...

@oristarA,

2 x 3 = 6
