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 28,862,669, 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 | 28,862,669 | |
| -1 | -28,862,669 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,862,669.
Example:
1 x 28,862,669 = 28,862,669
and
-1 x -28,862,669 = 28,862,669
Notice both answers equal 28,862,669
With that explanation out of the way, let's continue. Next, we take the number 28,862,669 and divide it by 2:
28,862,669 ÷ 2 = 14,431,334.5
If the quotient is a whole number, then 2 and 14,431,334.5 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 | 28,862,669 | |
| -1 | -28,862,669 |
Now, we try dividing 28,862,669 by 3:
28,862,669 ÷ 3 = 9,620,889.6667
If the quotient is a whole number, then 3 and 9,620,889.6667 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 | 28,862,669 | |
| -1 | -28,862,669 |
Let's try dividing by 4:
28,862,669 ÷ 4 = 7,215,667.25
If the quotient is a whole number, then 4 and 7,215,667.25 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 | 28,862,669 | |
| -1 | 28,862,669 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 101 | 313 | 913 | 1,111 | 3,443 | 8,383 | 25,979 | 31,613 | 92,213 | 285,769 | 347,743 | 2,623,879 | 28,862,669 |
| -1 | -11 | -83 | -101 | -313 | -913 | -1,111 | -3,443 | -8,383 | -25,979 | -31,613 | -92,213 | -285,769 | -347,743 | -2,623,879 | -28,862,669 |
