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 28,644,475, 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 | 28,644,475 | |
| -1 | -28,644,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,644,475.
Example:
1 x 28,644,475 = 28,644,475
and
-1 x -28,644,475 = 28,644,475
Notice both answers equal 28,644,475
With that explanation out of the way, let's continue. Next, we take the number 28,644,475 and divide it by 2:
28,644,475 ÷ 2 = 14,322,237.5
If the quotient is a whole number, then 2 and 14,322,237.5 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 | 28,644,475 | |
| -1 | -28,644,475 |
Now, we try dividing 28,644,475 by 3:
28,644,475 ÷ 3 = 9,548,158.3333
If the quotient is a whole number, then 3 and 9,548,158.3333 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 | 28,644,475 | |
| -1 | -28,644,475 |
Let's try dividing by 4:
28,644,475 ÷ 4 = 7,161,118.75
If the quotient is a whole number, then 4 and 7,161,118.75 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 | 28,644,475 | |
| -1 | 28,644,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 173 | 179 | 185 | 865 | 895 | 925 | 4,325 | 4,475 | 6,401 | 6,623 | 30,967 | 32,005 | 33,115 | 154,835 | 160,025 | 165,575 | 774,175 | 1,145,779 | 5,728,895 | 28,644,475 |
| -1 | -5 | -25 | -37 | -173 | -179 | -185 | -865 | -895 | -925 | -4,325 | -4,475 | -6,401 | -6,623 | -30,967 | -32,005 | -33,115 | -154,835 | -160,025 | -165,575 | -774,175 | -1,145,779 | -5,728,895 | -28,644,475 |
