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 22,870,115, 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 | 22,870,115 | |
| -1 | -22,870,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,870,115.
Example:
1 x 22,870,115 = 22,870,115
and
-1 x -22,870,115 = 22,870,115
Notice both answers equal 22,870,115
With that explanation out of the way, let's continue. Next, we take the number 22,870,115 and divide it by 2:
22,870,115 ÷ 2 = 11,435,057.5
If the quotient is a whole number, then 2 and 11,435,057.5 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 | 22,870,115 | |
| -1 | -22,870,115 |
Now, we try dividing 22,870,115 by 3:
22,870,115 ÷ 3 = 7,623,371.6667
If the quotient is a whole number, then 3 and 7,623,371.6667 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 | 22,870,115 | |
| -1 | -22,870,115 |
Let's try dividing by 4:
22,870,115 ÷ 4 = 5,717,528.75
If the quotient is a whole number, then 4 and 5,717,528.75 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 | 22,870,115 | |
| -1 | 22,870,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 233 | 293 | 335 | 1,165 | 1,465 | 15,611 | 19,631 | 68,269 | 78,055 | 98,155 | 341,345 | 4,574,023 | 22,870,115 |
| -1 | -5 | -67 | -233 | -293 | -335 | -1,165 | -1,465 | -15,611 | -19,631 | -68,269 | -78,055 | -98,155 | -341,345 | -4,574,023 | -22,870,115 |
