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 24,522,025, 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 | 24,522,025 | |
| -1 | -24,522,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,522,025.
Example:
1 x 24,522,025 = 24,522,025
and
-1 x -24,522,025 = 24,522,025
Notice both answers equal 24,522,025
With that explanation out of the way, let's continue. Next, we take the number 24,522,025 and divide it by 2:
24,522,025 ÷ 2 = 12,261,012.5
If the quotient is a whole number, then 2 and 12,261,012.5 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 | 24,522,025 | |
| -1 | -24,522,025 |
Now, we try dividing 24,522,025 by 3:
24,522,025 ÷ 3 = 8,174,008.3333
If the quotient is a whole number, then 3 and 8,174,008.3333 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 | 24,522,025 | |
| -1 | -24,522,025 |
Let's try dividing by 4:
24,522,025 ÷ 4 = 6,130,506.25
If the quotient is a whole number, then 4 and 6,130,506.25 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 | 24,522,025 | |
| -1 | 24,522,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 3,877 | 6,325 | 19,385 | 42,647 | 89,171 | 96,925 | 213,235 | 445,855 | 980,881 | 1,066,175 | 2,229,275 | 4,904,405 | 24,522,025 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -3,877 | -6,325 | -19,385 | -42,647 | -89,171 | -96,925 | -213,235 | -445,855 | -980,881 | -1,066,175 | -2,229,275 | -4,904,405 | -24,522,025 |
