If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
A factor is a number that divides evenly into another number with no remainder. 3 is a factor of 9. 4 is not a factor of 9.
Since the greatest 1-digit number is 9, the answer is 9 x 9 = 81.
A factor is a number such that it evenly divides a number. Example: Algebra: Let's say that we have a number, X. A factor of X would be a number (let's call this number f) such that it would divide X evenly without leaving a remainder. So, you can write X/f = n (where n is an integer) Arithmetic: Let's say that we have a number 9. A factor of 9 would be a number such that it would divide 9 evenly without leaving a remainder. By this definition, a factor of 9 would be 3 because 9/3 = 3<-- notice that this answer, 3, is an integer. Also, notice that this division does not leave behind any remainder. An example of a number that is NOT a factor of another number: Let's say that we have a number 9. A non-factor of 9 would be 6 because 9/6 does not leave behind a nice, whole number.
If the digital sum of any number finally add up to 9 then it will have 9 as a factor.
