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 15,883,763, 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 | 15,883,763 | |
| -1 | -15,883,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,883,763.
Example:
1 x 15,883,763 = 15,883,763
and
-1 x -15,883,763 = 15,883,763
Notice both answers equal 15,883,763
With that explanation out of the way, let's continue. Next, we take the number 15,883,763 and divide it by 2:
15,883,763 ÷ 2 = 7,941,881.5
If the quotient is a whole number, then 2 and 7,941,881.5 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 | 15,883,763 | |
| -1 | -15,883,763 |
Now, we try dividing 15,883,763 by 3:
15,883,763 ÷ 3 = 5,294,587.6667
If the quotient is a whole number, then 3 and 5,294,587.6667 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 | 15,883,763 | |
| -1 | -15,883,763 |
Let's try dividing by 4:
15,883,763 ÷ 4 = 3,970,940.75
If the quotient is a whole number, then 4 and 3,970,940.75 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 | 15,883,763 | |
| -1 | 15,883,763 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 127 | 889 | 1,051 | 2,159 | 7,357 | 15,113 | 17,867 | 125,069 | 133,477 | 934,339 | 2,269,109 | 15,883,763 |
| -1 | -7 | -17 | -119 | -127 | -889 | -1,051 | -2,159 | -7,357 | -15,113 | -17,867 | -125,069 | -133,477 | -934,339 | -2,269,109 | -15,883,763 |
