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 12,762,113, 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 | 12,762,113 | |
| -1 | -12,762,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,762,113.
Example:
1 x 12,762,113 = 12,762,113
and
-1 x -12,762,113 = 12,762,113
Notice both answers equal 12,762,113
With that explanation out of the way, let's continue. Next, we take the number 12,762,113 and divide it by 2:
12,762,113 ÷ 2 = 6,381,056.5
If the quotient is a whole number, then 2 and 6,381,056.5 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 | 12,762,113 | |
| -1 | -12,762,113 |
Now, we try dividing 12,762,113 by 3:
12,762,113 ÷ 3 = 4,254,037.6667
If the quotient is a whole number, then 3 and 4,254,037.6667 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 | 12,762,113 | |
| -1 | -12,762,113 |
Let's try dividing by 4:
12,762,113 ÷ 4 = 3,190,528.25
If the quotient is a whole number, then 4 and 3,190,528.25 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 | 12,762,113 | |
| -1 | 12,762,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 767 | 2,377 | 5,369 | 16,639 | 30,901 | 140,243 | 216,307 | 981,701 | 1,823,159 | 12,762,113 |
| -1 | -7 | -13 | -59 | -91 | -413 | -767 | -2,377 | -5,369 | -16,639 | -30,901 | -140,243 | -216,307 | -981,701 | -1,823,159 | -12,762,113 |
