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 268,562,827, 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 | 268,562,827 | |
| -1 | -268,562,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 268,562,827.
Example:
1 x 268,562,827 = 268,562,827
and
-1 x -268,562,827 = 268,562,827
Notice both answers equal 268,562,827
With that explanation out of the way, let's continue. Next, we take the number 268,562,827 and divide it by 2:
268,562,827 ÷ 2 = 134,281,413.5
If the quotient is a whole number, then 2 and 134,281,413.5 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 | 268,562,827 | |
| -1 | -268,562,827 |
Now, we try dividing 268,562,827 by 3:
268,562,827 ÷ 3 = 89,520,942.3333
If the quotient is a whole number, then 3 and 89,520,942.3333 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 | 268,562,827 | |
| -1 | -268,562,827 |
Let's try dividing by 4:
268,562,827 ÷ 4 = 67,140,706.75
If the quotient is a whole number, then 4 and 67,140,706.75 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 | 268,562,827 | |
| -1 | 268,562,827 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 403 | 467 | 1,427 | 6,071 | 14,477 | 18,551 | 44,237 | 188,201 | 575,081 | 666,409 | 8,663,317 | 20,658,679 | 268,562,827 |
| -1 | -13 | -31 | -403 | -467 | -1,427 | -6,071 | -14,477 | -18,551 | -44,237 | -188,201 | -575,081 | -666,409 | -8,663,317 | -20,658,679 | -268,562,827 |
