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 13,153,315, 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 | 13,153,315 | |
| -1 | -13,153,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,153,315.
Example:
1 x 13,153,315 = 13,153,315
and
-1 x -13,153,315 = 13,153,315
Notice both answers equal 13,153,315
With that explanation out of the way, let's continue. Next, we take the number 13,153,315 and divide it by 2:
13,153,315 ÷ 2 = 6,576,657.5
If the quotient is a whole number, then 2 and 6,576,657.5 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 | 13,153,315 | |
| -1 | -13,153,315 |
Now, we try dividing 13,153,315 by 3:
13,153,315 ÷ 3 = 4,384,438.3333
If the quotient is a whole number, then 3 and 4,384,438.3333 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 | 13,153,315 | |
| -1 | -13,153,315 |
Let's try dividing by 4:
13,153,315 ÷ 4 = 3,288,328.75
If the quotient is a whole number, then 4 and 3,288,328.75 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 | 13,153,315 | |
| -1 | 13,153,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 49 | 185 | 245 | 259 | 1,295 | 1,451 | 1,813 | 7,255 | 9,065 | 10,157 | 50,785 | 53,687 | 71,099 | 268,435 | 355,495 | 375,809 | 1,879,045 | 2,630,663 | 13,153,315 |
| -1 | -5 | -7 | -35 | -37 | -49 | -185 | -245 | -259 | -1,295 | -1,451 | -1,813 | -7,255 | -9,065 | -10,157 | -50,785 | -53,687 | -71,099 | -268,435 | -355,495 | -375,809 | -1,879,045 | -2,630,663 | -13,153,315 |
