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 15,516,053, 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 | 15,516,053 | |
| -1 | -15,516,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,516,053.
Example:
1 x 15,516,053 = 15,516,053
and
-1 x -15,516,053 = 15,516,053
Notice both answers equal 15,516,053
With that explanation out of the way, let's continue. Next, we take the number 15,516,053 and divide it by 2:
15,516,053 ÷ 2 = 7,758,026.5
If the quotient is a whole number, then 2 and 7,758,026.5 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 | 15,516,053 | |
| -1 | -15,516,053 |
Now, we try dividing 15,516,053 by 3:
15,516,053 ÷ 3 = 5,172,017.6667
If the quotient is a whole number, then 3 and 5,172,017.6667 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 | 15,516,053 | |
| -1 | -15,516,053 |
Let's try dividing by 4:
15,516,053 ÷ 4 = 3,879,013.25
If the quotient is a whole number, then 4 and 3,879,013.25 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 | 15,516,053 | |
| -1 | 15,516,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 2,737 | 5,669 | 39,683 | 96,373 | 130,387 | 674,611 | 912,709 | 2,216,579 | 15,516,053 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -2,737 | -5,669 | -39,683 | -96,373 | -130,387 | -674,611 | -912,709 | -2,216,579 | -15,516,053 |
