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 13,549,415, 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 | 13,549,415 | |
| -1 | -13,549,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,549,415.
Example:
1 x 13,549,415 = 13,549,415
and
-1 x -13,549,415 = 13,549,415
Notice both answers equal 13,549,415
With that explanation out of the way, let's continue. Next, we take the number 13,549,415 and divide it by 2:
13,549,415 ÷ 2 = 6,774,707.5
If the quotient is a whole number, then 2 and 6,774,707.5 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 | 13,549,415 | |
| -1 | -13,549,415 |
Now, we try dividing 13,549,415 by 3:
13,549,415 ÷ 3 = 4,516,471.6667
If the quotient is a whole number, then 3 and 4,516,471.6667 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 | 13,549,415 | |
| -1 | -13,549,415 |
Let's try dividing by 4:
13,549,415 ÷ 4 = 3,387,353.75
If the quotient is a whole number, then 4 and 3,387,353.75 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 | 13,549,415 | |
| -1 | 13,549,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 10,711 | 53,555 | 117,821 | 246,353 | 589,105 | 1,231,765 | 2,709,883 | 13,549,415 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -10,711 | -53,555 | -117,821 | -246,353 | -589,105 | -1,231,765 | -2,709,883 | -13,549,415 |
