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 22,420,625, 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 | 22,420,625 | |
| -1 | -22,420,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,420,625.
Example:
1 x 22,420,625 = 22,420,625
and
-1 x -22,420,625 = 22,420,625
Notice both answers equal 22,420,625
With that explanation out of the way, let's continue. Next, we take the number 22,420,625 and divide it by 2:
22,420,625 ÷ 2 = 11,210,312.5
If the quotient is a whole number, then 2 and 11,210,312.5 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 | 22,420,625 | |
| -1 | -22,420,625 |
Now, we try dividing 22,420,625 by 3:
22,420,625 ÷ 3 = 7,473,541.6667
If the quotient is a whole number, then 3 and 7,473,541.6667 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 | 22,420,625 | |
| -1 | -22,420,625 |
Let's try dividing by 4:
22,420,625 ÷ 4 = 5,605,156.25
If the quotient is a whole number, then 4 and 5,605,156.25 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 | 22,420,625 | |
| -1 | 22,420,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 625 | 725 | 1,237 | 3,625 | 6,185 | 18,125 | 30,925 | 35,873 | 154,625 | 179,365 | 773,125 | 896,825 | 4,484,125 | 22,420,625 |
| -1 | -5 | -25 | -29 | -125 | -145 | -625 | -725 | -1,237 | -3,625 | -6,185 | -18,125 | -30,925 | -35,873 | -154,625 | -179,365 | -773,125 | -896,825 | -4,484,125 | -22,420,625 |
