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 24,226,445, 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 | 24,226,445 | |
| -1 | -24,226,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,226,445.
Example:
1 x 24,226,445 = 24,226,445
and
-1 x -24,226,445 = 24,226,445
Notice both answers equal 24,226,445
With that explanation out of the way, let's continue. Next, we take the number 24,226,445 and divide it by 2:
24,226,445 ÷ 2 = 12,113,222.5
If the quotient is a whole number, then 2 and 12,113,222.5 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 | 24,226,445 | |
| -1 | -24,226,445 |
Now, we try dividing 24,226,445 by 3:
24,226,445 ÷ 3 = 8,075,481.6667
If the quotient is a whole number, then 3 and 8,075,481.6667 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 | 24,226,445 | |
| -1 | -24,226,445 |
Let's try dividing by 4:
24,226,445 ÷ 4 = 6,056,611.25
If the quotient is a whole number, then 4 and 6,056,611.25 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 | 24,226,445 | |
| -1 | 24,226,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 421 | 677 | 2,105 | 3,385 | 7,157 | 11,509 | 35,785 | 57,545 | 285,017 | 1,425,085 | 4,845,289 | 24,226,445 |
| -1 | -5 | -17 | -85 | -421 | -677 | -2,105 | -3,385 | -7,157 | -11,509 | -35,785 | -57,545 | -285,017 | -1,425,085 | -4,845,289 | -24,226,445 |
