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 262,354,147, 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 | 262,354,147 | |
| -1 | -262,354,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,354,147.
Example:
1 x 262,354,147 = 262,354,147
and
-1 x -262,354,147 = 262,354,147
Notice both answers equal 262,354,147
With that explanation out of the way, let's continue. Next, we take the number 262,354,147 and divide it by 2:
262,354,147 ÷ 2 = 131,177,073.5
If the quotient is a whole number, then 2 and 131,177,073.5 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 | 262,354,147 | |
| -1 | -262,354,147 |
Now, we try dividing 262,354,147 by 3:
262,354,147 ÷ 3 = 87,451,382.3333
If the quotient is a whole number, then 3 and 87,451,382.3333 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 | 262,354,147 | |
| -1 | -262,354,147 |
Let's try dividing by 4:
262,354,147 ÷ 4 = 65,588,536.75
If the quotient is a whole number, then 4 and 65,588,536.75 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 | 262,354,147 | |
| -1 | 262,354,147 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 31 | 209 | 341 | 589 | 6,479 | 40,493 | 445,423 | 769,367 | 1,255,283 | 8,463,037 | 13,808,113 | 23,850,377 | 262,354,147 |
| -1 | -11 | -19 | -31 | -209 | -341 | -589 | -6,479 | -40,493 | -445,423 | -769,367 | -1,255,283 | -8,463,037 | -13,808,113 | -23,850,377 | -262,354,147 |
