Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 9,001,675, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 9,001,675 | |
| -1 | -9,001,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,001,675.
Example:
1 x 9,001,675 = 9,001,675
and
-1 x -9,001,675 = 9,001,675
Notice both answers equal 9,001,675
With that explanation out of the way, let's continue. Next, we take the number 9,001,675 and divide it by 2:
9,001,675 ÷ 2 = 4,500,837.5
If the quotient is a whole number, then 2 and 4,500,837.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 9,001,675 | |
| -1 | -9,001,675 |
Now, we try dividing 9,001,675 by 3:
9,001,675 ÷ 3 = 3,000,558.3333
If the quotient is a whole number, then 3 and 3,000,558.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 9,001,675 | |
| -1 | -9,001,675 |
Let's try dividing by 4:
9,001,675 ÷ 4 = 2,250,418.75
If the quotient is a whole number, then 4 and 2,250,418.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 9,001,675 | |
| -1 | 9,001,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 163 | 235 | 815 | 1,175 | 2,209 | 4,075 | 7,661 | 11,045 | 38,305 | 55,225 | 191,525 | 360,067 | 1,800,335 | 9,001,675 |
| -1 | -5 | -25 | -47 | -163 | -235 | -815 | -1,175 | -2,209 | -4,075 | -7,661 | -11,045 | -38,305 | -55,225 | -191,525 | -360,067 | -1,800,335 | -9,001,675 |
