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 28,042,267, 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 | 28,042,267 | |
| -1 | -28,042,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,042,267.
Example:
1 x 28,042,267 = 28,042,267
and
-1 x -28,042,267 = 28,042,267
Notice both answers equal 28,042,267
With that explanation out of the way, let's continue. Next, we take the number 28,042,267 and divide it by 2:
28,042,267 ÷ 2 = 14,021,133.5
If the quotient is a whole number, then 2 and 14,021,133.5 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 | 28,042,267 | |
| -1 | -28,042,267 |
Now, we try dividing 28,042,267 by 3:
28,042,267 ÷ 3 = 9,347,422.3333
If the quotient is a whole number, then 3 and 9,347,422.3333 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 | 28,042,267 | |
| -1 | -28,042,267 |
Let's try dividing by 4:
28,042,267 ÷ 4 = 7,010,566.75
If the quotient is a whole number, then 4 and 7,010,566.75 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 | 28,042,267 | |
| -1 | 28,042,267 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 271 | 409 | 2,981 | 4,499 | 6,233 | 9,407 | 68,563 | 103,477 | 110,839 | 1,219,229 | 2,549,297 | 28,042,267 |
| -1 | -11 | -23 | -253 | -271 | -409 | -2,981 | -4,499 | -6,233 | -9,407 | -68,563 | -103,477 | -110,839 | -1,219,229 | -2,549,297 | -28,042,267 |
