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 15,146,443, 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 | 15,146,443 | |
| -1 | -15,146,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,146,443.
Example:
1 x 15,146,443 = 15,146,443
and
-1 x -15,146,443 = 15,146,443
Notice both answers equal 15,146,443
With that explanation out of the way, let's continue. Next, we take the number 15,146,443 and divide it by 2:
15,146,443 ÷ 2 = 7,573,221.5
If the quotient is a whole number, then 2 and 7,573,221.5 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 | 15,146,443 | |
| -1 | -15,146,443 |
Now, we try dividing 15,146,443 by 3:
15,146,443 ÷ 3 = 5,048,814.3333
If the quotient is a whole number, then 3 and 5,048,814.3333 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 | 15,146,443 | |
| -1 | -15,146,443 |
Let's try dividing by 4:
15,146,443 ÷ 4 = 3,786,610.75
If the quotient is a whole number, then 4 and 3,786,610.75 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 | 15,146,443 | |
| -1 | 15,146,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 179 | 283 | 299 | 2,327 | 3,679 | 4,117 | 6,509 | 50,657 | 53,521 | 84,617 | 658,541 | 1,165,111 | 15,146,443 |
| -1 | -13 | -23 | -179 | -283 | -299 | -2,327 | -3,679 | -4,117 | -6,509 | -50,657 | -53,521 | -84,617 | -658,541 | -1,165,111 | -15,146,443 |
