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 11,738,069, 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 | 11,738,069 | |
| -1 | -11,738,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,738,069.
Example:
1 x 11,738,069 = 11,738,069
and
-1 x -11,738,069 = 11,738,069
Notice both answers equal 11,738,069
With that explanation out of the way, let's continue. Next, we take the number 11,738,069 and divide it by 2:
11,738,069 ÷ 2 = 5,869,034.5
If the quotient is a whole number, then 2 and 5,869,034.5 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 | 11,738,069 | |
| -1 | -11,738,069 |
Now, we try dividing 11,738,069 by 3:
11,738,069 ÷ 3 = 3,912,689.6667
If the quotient is a whole number, then 3 and 3,912,689.6667 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 | 11,738,069 | |
| -1 | -11,738,069 |
Let's try dividing by 4:
11,738,069 ÷ 4 = 2,934,517.25
If the quotient is a whole number, then 4 and 2,934,517.25 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 | 11,738,069 | |
| -1 | 11,738,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 53 | 203 | 371 | 1,091 | 1,537 | 7,637 | 10,759 | 31,639 | 57,823 | 221,473 | 404,761 | 1,676,867 | 11,738,069 |
| -1 | -7 | -29 | -53 | -203 | -371 | -1,091 | -1,537 | -7,637 | -10,759 | -31,639 | -57,823 | -221,473 | -404,761 | -1,676,867 | -11,738,069 |
