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 28,823,347, 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 | 28,823,347 | |
| -1 | -28,823,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,823,347.
Example:
1 x 28,823,347 = 28,823,347
and
-1 x -28,823,347 = 28,823,347
Notice both answers equal 28,823,347
With that explanation out of the way, let's continue. Next, we take the number 28,823,347 and divide it by 2:
28,823,347 ÷ 2 = 14,411,673.5
If the quotient is a whole number, then 2 and 14,411,673.5 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 | 28,823,347 | |
| -1 | -28,823,347 |
Now, we try dividing 28,823,347 by 3:
28,823,347 ÷ 3 = 9,607,782.3333
If the quotient is a whole number, then 3 and 9,607,782.3333 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 | 28,823,347 | |
| -1 | -28,823,347 |
Let's try dividing by 4:
28,823,347 ÷ 4 = 7,205,836.75
If the quotient is a whole number, then 4 and 7,205,836.75 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 | 28,823,347 | |
| -1 | 28,823,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 2,737 | 10,531 | 73,717 | 179,027 | 242,213 | 1,253,189 | 1,695,491 | 4,117,621 | 28,823,347 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -2,737 | -10,531 | -73,717 | -179,027 | -242,213 | -1,253,189 | -1,695,491 | -4,117,621 | -28,823,347 |
