Their product.
18. 1 and18 add to 19, 2 and 9 add to 11, and 3 and 6 add to 9.
Every number except zero is a factor of every other number. Usually this kind of question is intended as a question about integral factors, those that can be paired with another integer to produce the number as a product. In that sense, 9 is not an integral factor of 11, because the paired number with 9 is 11/9, a number that is not an integer.
A factor = number which can be divided into the given number with no remainder eg 3, 9, 11, 33, 99 the factor of 99 is 9.
11 is a prime number, meaning its only factors are 1 and itself. So, the greatest common factor of 9 and 11 is 1.
The answer is 18.Factors 1*18=18 Factors added 1+18=192*9=18 2+9=113*6=18 3+6=9
Factors of 9: 1, 3, 9Factors of 19: 1, 19GCF (9, 19) = 1
11 and 9 is a factor pair for 99. 11 and x^9 is a factor pair for 11x^9.
9 enlarged by a factor of a number is 9*y

It can be. 9 is a factor of 18.
No, 3 is a factor of 9.
No, 9 is a factor of 36.
