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 15,041,299, 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 | 15,041,299 | |
| -1 | -15,041,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,041,299.
Example:
1 x 15,041,299 = 15,041,299
and
-1 x -15,041,299 = 15,041,299
Notice both answers equal 15,041,299
With that explanation out of the way, let's continue. Next, we take the number 15,041,299 and divide it by 2:
15,041,299 ÷ 2 = 7,520,649.5
If the quotient is a whole number, then 2 and 7,520,649.5 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 | 15,041,299 | |
| -1 | -15,041,299 |
Now, we try dividing 15,041,299 by 3:
15,041,299 ÷ 3 = 5,013,766.3333
If the quotient is a whole number, then 3 and 5,013,766.3333 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 | 15,041,299 | |
| -1 | -15,041,299 |
Let's try dividing by 4:
15,041,299 ÷ 4 = 3,760,324.75
If the quotient is a whole number, then 4 and 3,760,324.75 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 | 15,041,299 | |
| -1 | 15,041,299 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 67 | 91 | 469 | 871 | 2,467 | 6,097 | 17,269 | 32,071 | 165,289 | 224,497 | 1,157,023 | 2,148,757 | 15,041,299 |
| -1 | -7 | -13 | -67 | -91 | -469 | -871 | -2,467 | -6,097 | -17,269 | -32,071 | -165,289 | -224,497 | -1,157,023 | -2,148,757 | -15,041,299 |
