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 15,705,343, 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 | 15,705,343 | |
| -1 | -15,705,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,705,343.
Example:
1 x 15,705,343 = 15,705,343
and
-1 x -15,705,343 = 15,705,343
Notice both answers equal 15,705,343
With that explanation out of the way, let's continue. Next, we take the number 15,705,343 and divide it by 2:
15,705,343 ÷ 2 = 7,852,671.5
If the quotient is a whole number, then 2 and 7,852,671.5 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 | 15,705,343 | |
| -1 | -15,705,343 |
Now, we try dividing 15,705,343 by 3:
15,705,343 ÷ 3 = 5,235,114.3333
If the quotient is a whole number, then 3 and 5,235,114.3333 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 | 15,705,343 | |
| -1 | -15,705,343 |
Let's try dividing by 4:
15,705,343 ÷ 4 = 3,926,335.75
If the quotient is a whole number, then 4 and 3,926,335.75 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 | 15,705,343 | |
| -1 | 15,705,343 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 83 | 433 | 437 | 1,577 | 1,909 | 8,227 | 9,959 | 35,939 | 36,271 | 189,221 | 682,841 | 826,597 | 15,705,343 |
| -1 | -19 | -23 | -83 | -433 | -437 | -1,577 | -1,909 | -8,227 | -9,959 | -35,939 | -36,271 | -189,221 | -682,841 | -826,597 | -15,705,343 |
