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 10,124,543, 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 | 10,124,543 | |
| -1 | -10,124,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,124,543.
Example:
1 x 10,124,543 = 10,124,543
and
-1 x -10,124,543 = 10,124,543
Notice both answers equal 10,124,543
With that explanation out of the way, let's continue. Next, we take the number 10,124,543 and divide it by 2:
10,124,543 ÷ 2 = 5,062,271.5
If the quotient is a whole number, then 2 and 5,062,271.5 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 | 10,124,543 | |
| -1 | -10,124,543 |
Now, we try dividing 10,124,543 by 3:
10,124,543 ÷ 3 = 3,374,847.6667
If the quotient is a whole number, then 3 and 3,374,847.6667 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 | 10,124,543 | |
| -1 | -10,124,543 |
Let's try dividing by 4:
10,124,543 ÷ 4 = 2,531,135.75
If the quotient is a whole number, then 4 and 2,531,135.75 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 | 10,124,543 | |
| -1 | 10,124,543 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 101 | 143 | 701 | 1,111 | 1,313 | 7,711 | 9,113 | 14,443 | 70,801 | 100,243 | 778,811 | 920,413 | 10,124,543 |
| -1 | -11 | -13 | -101 | -143 | -701 | -1,111 | -1,313 | -7,711 | -9,113 | -14,443 | -70,801 | -100,243 | -778,811 | -920,413 | -10,124,543 |
