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 22,701,385, 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 | 22,701,385 | |
| -1 | -22,701,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,701,385.
Example:
1 x 22,701,385 = 22,701,385
and
-1 x -22,701,385 = 22,701,385
Notice both answers equal 22,701,385
With that explanation out of the way, let's continue. Next, we take the number 22,701,385 and divide it by 2:
22,701,385 ÷ 2 = 11,350,692.5
If the quotient is a whole number, then 2 and 11,350,692.5 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 | 22,701,385 | |
| -1 | -22,701,385 |
Now, we try dividing 22,701,385 by 3:
22,701,385 ÷ 3 = 7,567,128.3333
If the quotient is a whole number, then 3 and 7,567,128.3333 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 | 22,701,385 | |
| -1 | -22,701,385 |
Let's try dividing by 4:
22,701,385 ÷ 4 = 5,675,346.25
If the quotient is a whole number, then 4 and 5,675,346.25 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 | 22,701,385 | |
| -1 | 22,701,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 491 | 1,321 | 2,455 | 3,437 | 6,605 | 9,247 | 17,185 | 46,235 | 648,611 | 3,243,055 | 4,540,277 | 22,701,385 |
| -1 | -5 | -7 | -35 | -491 | -1,321 | -2,455 | -3,437 | -6,605 | -9,247 | -17,185 | -46,235 | -648,611 | -3,243,055 | -4,540,277 | -22,701,385 |
