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 13,510,189, 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 | 13,510,189 | |
| -1 | -13,510,189 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,510,189.
Example:
1 x 13,510,189 = 13,510,189
and
-1 x -13,510,189 = 13,510,189
Notice both answers equal 13,510,189
With that explanation out of the way, let's continue. Next, we take the number 13,510,189 and divide it by 2:
13,510,189 ÷ 2 = 6,755,094.5
If the quotient is a whole number, then 2 and 6,755,094.5 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 | 13,510,189 | |
| -1 | -13,510,189 |
Now, we try dividing 13,510,189 by 3:
13,510,189 ÷ 3 = 4,503,396.3333
If the quotient is a whole number, then 3 and 4,503,396.3333 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 | 13,510,189 | |
| -1 | -13,510,189 |
Let's try dividing by 4:
13,510,189 ÷ 4 = 3,377,547.25
If the quotient is a whole number, then 4 and 3,377,547.25 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 | 13,510,189 | |
| -1 | 13,510,189 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 10,321 | 72,247 | 113,531 | 175,457 | 794,717 | 1,228,199 | 1,930,027 | 13,510,189 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -10,321 | -72,247 | -113,531 | -175,457 | -794,717 | -1,228,199 | -1,930,027 | -13,510,189 |
