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 15,620,033, 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 | 15,620,033 | |
| -1 | -15,620,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,620,033.
Example:
1 x 15,620,033 = 15,620,033
and
-1 x -15,620,033 = 15,620,033
Notice both answers equal 15,620,033
With that explanation out of the way, let's continue. Next, we take the number 15,620,033 and divide it by 2:
15,620,033 ÷ 2 = 7,810,016.5
If the quotient is a whole number, then 2 and 7,810,016.5 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 | 15,620,033 | |
| -1 | -15,620,033 |
Now, we try dividing 15,620,033 by 3:
15,620,033 ÷ 3 = 5,206,677.6667
If the quotient is a whole number, then 3 and 5,206,677.6667 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 | 15,620,033 | |
| -1 | -15,620,033 |
Let's try dividing by 4:
15,620,033 ÷ 4 = 3,905,008.25
If the quotient is a whole number, then 4 and 3,905,008.25 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 | 15,620,033 | |
| -1 | 15,620,033 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 209 | 247 | 2,717 | 5,749 | 63,239 | 74,737 | 109,231 | 822,107 | 1,201,541 | 1,420,003 | 15,620,033 |
| -1 | -11 | -13 | -19 | -143 | -209 | -247 | -2,717 | -5,749 | -63,239 | -74,737 | -109,231 | -822,107 | -1,201,541 | -1,420,003 | -15,620,033 |
