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 9,074,651, 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 | 9,074,651 | |
| -1 | -9,074,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,074,651.
Example:
1 x 9,074,651 = 9,074,651
and
-1 x -9,074,651 = 9,074,651
Notice both answers equal 9,074,651
With that explanation out of the way, let's continue. Next, we take the number 9,074,651 and divide it by 2:
9,074,651 ÷ 2 = 4,537,325.5
If the quotient is a whole number, then 2 and 4,537,325.5 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 | 9,074,651 | |
| -1 | -9,074,651 |
Now, we try dividing 9,074,651 by 3:
9,074,651 ÷ 3 = 3,024,883.6667
If the quotient is a whole number, then 3 and 3,024,883.6667 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 | 9,074,651 | |
| -1 | -9,074,651 |
Let's try dividing by 4:
9,074,651 ÷ 4 = 2,268,662.75
If the quotient is a whole number, then 4 and 2,268,662.75 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 | 9,074,651 | |
| -1 | 9,074,651 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 79 | 233 | 493 | 1,343 | 2,291 | 3,961 | 6,757 | 18,407 | 38,947 | 114,869 | 312,919 | 533,803 | 9,074,651 |
| -1 | -17 | -29 | -79 | -233 | -493 | -1,343 | -2,291 | -3,961 | -6,757 | -18,407 | -38,947 | -114,869 | -312,919 | -533,803 | -9,074,651 |
