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 262,447,411, 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 | 262,447,411 | |
| -1 | -262,447,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,447,411.
Example:
1 x 262,447,411 = 262,447,411
and
-1 x -262,447,411 = 262,447,411
Notice both answers equal 262,447,411
With that explanation out of the way, let's continue. Next, we take the number 262,447,411 and divide it by 2:
262,447,411 ÷ 2 = 131,223,705.5
If the quotient is a whole number, then 2 and 131,223,705.5 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 | 262,447,411 | |
| -1 | -262,447,411 |
Now, we try dividing 262,447,411 by 3:
262,447,411 ÷ 3 = 87,482,470.3333
If the quotient is a whole number, then 3 and 87,482,470.3333 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 | 262,447,411 | |
| -1 | -262,447,411 |
Let's try dividing by 4:
262,447,411 ÷ 4 = 65,611,852.75
If the quotient is a whole number, then 4 and 65,611,852.75 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 | 262,447,411 | |
| -1 | 262,447,411 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 83 | 391 | 1,411 | 1,909 | 8,087 | 32,453 | 137,479 | 186,001 | 671,221 | 3,162,017 | 11,410,757 | 15,438,083 | 262,447,411 |
| -1 | -17 | -23 | -83 | -391 | -1,411 | -1,909 | -8,087 | -32,453 | -137,479 | -186,001 | -671,221 | -3,162,017 | -11,410,757 | -15,438,083 | -262,447,411 |
