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 262,477,637, 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 | 262,477,637 | |
| -1 | -262,477,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,477,637.
Example:
1 x 262,477,637 = 262,477,637
and
-1 x -262,477,637 = 262,477,637
Notice both answers equal 262,477,637
With that explanation out of the way, let's continue. Next, we take the number 262,477,637 and divide it by 2:
262,477,637 ÷ 2 = 131,238,818.5
If the quotient is a whole number, then 2 and 131,238,818.5 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 | 262,477,637 | |
| -1 | -262,477,637 |
Now, we try dividing 262,477,637 by 3:
262,477,637 ÷ 3 = 87,492,545.6667
If the quotient is a whole number, then 3 and 87,492,545.6667 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 | 262,477,637 | |
| -1 | -262,477,637 |
Let's try dividing by 4:
262,477,637 ÷ 4 = 65,619,409.25
If the quotient is a whole number, then 4 and 65,619,409.25 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 | 262,477,637 | |
| -1 | 262,477,637 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 493 | 587 | 907 | 9,979 | 15,419 | 17,023 | 26,303 | 289,391 | 447,151 | 532,409 | 9,050,953 | 15,439,861 | 262,477,637 |
| -1 | -17 | -29 | -493 | -587 | -907 | -9,979 | -15,419 | -17,023 | -26,303 | -289,391 | -447,151 | -532,409 | -9,050,953 | -15,439,861 | -262,477,637 |
