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 23,969,225, 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 | 23,969,225 | |
| -1 | -23,969,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,969,225.
Example:
1 x 23,969,225 = 23,969,225
and
-1 x -23,969,225 = 23,969,225
Notice both answers equal 23,969,225
With that explanation out of the way, let's continue. Next, we take the number 23,969,225 and divide it by 2:
23,969,225 ÷ 2 = 11,984,612.5
If the quotient is a whole number, then 2 and 11,984,612.5 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 | 23,969,225 | |
| -1 | -23,969,225 |
Now, we try dividing 23,969,225 by 3:
23,969,225 ÷ 3 = 7,989,741.6667
If the quotient is a whole number, then 3 and 7,989,741.6667 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 | 23,969,225 | |
| -1 | -23,969,225 |
Let's try dividing by 4:
23,969,225 ÷ 4 = 5,992,306.25
If the quotient is a whole number, then 4 and 5,992,306.25 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 | 23,969,225 | |
| -1 | 23,969,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 725 | 1,015 | 4,723 | 5,075 | 23,615 | 33,061 | 118,075 | 136,967 | 165,305 | 684,835 | 826,525 | 958,769 | 3,424,175 | 4,793,845 | 23,969,225 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -725 | -1,015 | -4,723 | -5,075 | -23,615 | -33,061 | -118,075 | -136,967 | -165,305 | -684,835 | -826,525 | -958,769 | -3,424,175 | -4,793,845 | -23,969,225 |
