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 15,533,455, 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 | 15,533,455 | |
| -1 | -15,533,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,533,455.
Example:
1 x 15,533,455 = 15,533,455
and
-1 x -15,533,455 = 15,533,455
Notice both answers equal 15,533,455
With that explanation out of the way, let's continue. Next, we take the number 15,533,455 and divide it by 2:
15,533,455 ÷ 2 = 7,766,727.5
If the quotient is a whole number, then 2 and 7,766,727.5 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 | 15,533,455 | |
| -1 | -15,533,455 |
Now, we try dividing 15,533,455 by 3:
15,533,455 ÷ 3 = 5,177,818.3333
If the quotient is a whole number, then 3 and 5,177,818.3333 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 | 15,533,455 | |
| -1 | -15,533,455 |
Let's try dividing by 4:
15,533,455 ÷ 4 = 3,883,363.75
If the quotient is a whole number, then 4 and 3,883,363.75 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 | 15,533,455 | |
| -1 | 15,533,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 347 | 1,279 | 1,735 | 2,429 | 6,395 | 8,953 | 12,145 | 44,765 | 443,813 | 2,219,065 | 3,106,691 | 15,533,455 |
| -1 | -5 | -7 | -35 | -347 | -1,279 | -1,735 | -2,429 | -6,395 | -8,953 | -12,145 | -44,765 | -443,813 | -2,219,065 | -3,106,691 | -15,533,455 |
