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 23,054,159, 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 | 23,054,159 | |
| -1 | -23,054,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,054,159.
Example:
1 x 23,054,159 = 23,054,159
and
-1 x -23,054,159 = 23,054,159
Notice both answers equal 23,054,159
With that explanation out of the way, let's continue. Next, we take the number 23,054,159 and divide it by 2:
23,054,159 ÷ 2 = 11,527,079.5
If the quotient is a whole number, then 2 and 11,527,079.5 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 | 23,054,159 | |
| -1 | -23,054,159 |
Now, we try dividing 23,054,159 by 3:
23,054,159 ÷ 3 = 7,684,719.6667
If the quotient is a whole number, then 3 and 7,684,719.6667 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 | 23,054,159 | |
| -1 | -23,054,159 |
Let's try dividing by 4:
23,054,159 ÷ 4 = 5,763,539.75
If the quotient is a whole number, then 4 and 5,763,539.75 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 | 23,054,159 | |
| -1 | 23,054,159 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 101 | 463 | 493 | 1,717 | 2,929 | 7,871 | 13,427 | 46,763 | 49,793 | 228,259 | 794,971 | 1,356,127 | 23,054,159 |
| -1 | -17 | -29 | -101 | -463 | -493 | -1,717 | -2,929 | -7,871 | -13,427 | -46,763 | -49,793 | -228,259 | -794,971 | -1,356,127 | -23,054,159 |
