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 22,700,185, 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 | 22,700,185 | |
| -1 | -22,700,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,700,185.
Example:
1 x 22,700,185 = 22,700,185
and
-1 x -22,700,185 = 22,700,185
Notice both answers equal 22,700,185
With that explanation out of the way, let's continue. Next, we take the number 22,700,185 and divide it by 2:
22,700,185 ÷ 2 = 11,350,092.5
If the quotient is a whole number, then 2 and 11,350,092.5 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 | 22,700,185 | |
| -1 | -22,700,185 |
Now, we try dividing 22,700,185 by 3:
22,700,185 ÷ 3 = 7,566,728.3333
If the quotient is a whole number, then 3 and 7,566,728.3333 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 | 22,700,185 | |
| -1 | -22,700,185 |
Let's try dividing by 4:
22,700,185 ÷ 4 = 5,675,046.25
If the quotient is a whole number, then 4 and 5,675,046.25 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 | 22,700,185 | |
| -1 | 22,700,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 493 | 2,465 | 9,209 | 46,045 | 156,553 | 267,061 | 782,765 | 1,335,305 | 4,540,037 | 22,700,185 |
| -1 | -5 | -17 | -29 | -85 | -145 | -493 | -2,465 | -9,209 | -46,045 | -156,553 | -267,061 | -782,765 | -1,335,305 | -4,540,037 | -22,700,185 |
