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 11,437,877, 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 | 11,437,877 | |
| -1 | -11,437,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,437,877.
Example:
1 x 11,437,877 = 11,437,877
and
-1 x -11,437,877 = 11,437,877
Notice both answers equal 11,437,877
With that explanation out of the way, let's continue. Next, we take the number 11,437,877 and divide it by 2:
11,437,877 ÷ 2 = 5,718,938.5
If the quotient is a whole number, then 2 and 5,718,938.5 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 | 11,437,877 | |
| -1 | -11,437,877 |
Now, we try dividing 11,437,877 by 3:
11,437,877 ÷ 3 = 3,812,625.6667
If the quotient is a whole number, then 3 and 3,812,625.6667 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 | 11,437,877 | |
| -1 | -11,437,877 |
Let's try dividing by 4:
11,437,877 ÷ 4 = 2,859,469.25
If the quotient is a whole number, then 4 and 2,859,469.25 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 | 11,437,877 | |
| -1 | 11,437,877 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 53 | 253 | 583 | 853 | 1,219 | 9,383 | 13,409 | 19,619 | 45,209 | 215,809 | 497,299 | 1,039,807 | 11,437,877 |
| -1 | -11 | -23 | -53 | -253 | -583 | -853 | -1,219 | -9,383 | -13,409 | -19,619 | -45,209 | -215,809 | -497,299 | -1,039,807 | -11,437,877 |
