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 22,874,579, 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 | 22,874,579 | |
| -1 | -22,874,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,874,579.
Example:
1 x 22,874,579 = 22,874,579
and
-1 x -22,874,579 = 22,874,579
Notice both answers equal 22,874,579
With that explanation out of the way, let's continue. Next, we take the number 22,874,579 and divide it by 2:
22,874,579 ÷ 2 = 11,437,289.5
If the quotient is a whole number, then 2 and 11,437,289.5 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 | 22,874,579 | |
| -1 | -22,874,579 |
Now, we try dividing 22,874,579 by 3:
22,874,579 ÷ 3 = 7,624,859.6667
If the quotient is a whole number, then 3 and 7,624,859.6667 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 | 22,874,579 | |
| -1 | -22,874,579 |
Let's try dividing by 4:
22,874,579 ÷ 4 = 5,718,644.75
If the quotient is a whole number, then 4 and 5,718,644.75 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 | 22,874,579 | |
| -1 | 22,874,579 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 173 | 1,211 | 1,453 | 2,249 | 10,171 | 15,743 | 18,889 | 132,223 | 251,369 | 1,759,583 | 3,267,797 | 22,874,579 |
| -1 | -7 | -13 | -91 | -173 | -1,211 | -1,453 | -2,249 | -10,171 | -15,743 | -18,889 | -132,223 | -251,369 | -1,759,583 | -3,267,797 | -22,874,579 |
