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 13,454,633, 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 | 13,454,633 | |
| -1 | -13,454,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,454,633.
Example:
1 x 13,454,633 = 13,454,633
and
-1 x -13,454,633 = 13,454,633
Notice both answers equal 13,454,633
With that explanation out of the way, let's continue. Next, we take the number 13,454,633 and divide it by 2:
13,454,633 ÷ 2 = 6,727,316.5
If the quotient is a whole number, then 2 and 6,727,316.5 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 | 13,454,633 | |
| -1 | -13,454,633 |
Now, we try dividing 13,454,633 by 3:
13,454,633 ÷ 3 = 4,484,877.6667
If the quotient is a whole number, then 3 and 4,484,877.6667 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 | 13,454,633 | |
| -1 | -13,454,633 |
Let's try dividing by 4:
13,454,633 ÷ 4 = 3,363,658.25
If the quotient is a whole number, then 4 and 3,363,658.25 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 | 13,454,633 | |
| -1 | 13,454,633 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 109 | 137 | 901 | 1,853 | 2,329 | 5,777 | 7,261 | 14,933 | 98,209 | 123,437 | 253,861 | 791,449 | 13,454,633 |
| -1 | -17 | -53 | -109 | -137 | -901 | -1,853 | -2,329 | -5,777 | -7,261 | -14,933 | -98,209 | -123,437 | -253,861 | -791,449 | -13,454,633 |
