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 131,633,453, 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 | 131,633,453 | |
| -1 | -131,633,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,633,453.
Example:
1 x 131,633,453 = 131,633,453
and
-1 x -131,633,453 = 131,633,453
Notice both answers equal 131,633,453
With that explanation out of the way, let's continue. Next, we take the number 131,633,453 and divide it by 2:
131,633,453 ÷ 2 = 65,816,726.5
If the quotient is a whole number, then 2 and 65,816,726.5 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 | 131,633,453 | |
| -1 | -131,633,453 |
Now, we try dividing 131,633,453 by 3:
131,633,453 ÷ 3 = 43,877,817.6667
If the quotient is a whole number, then 3 and 43,877,817.6667 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 | 131,633,453 | |
| -1 | -131,633,453 |
Let's try dividing by 4:
131,633,453 ÷ 4 = 32,908,363.25
If the quotient is a whole number, then 4 and 32,908,363.25 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 | 131,633,453 | |
| -1 | 131,633,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 343 | 359 | 1,069 | 2,513 | 7,483 | 17,591 | 52,381 | 123,137 | 366,667 | 383,771 | 2,686,397 | 18,804,779 | 131,633,453 |
| -1 | -7 | -49 | -343 | -359 | -1,069 | -2,513 | -7,483 | -17,591 | -52,381 | -123,137 | -366,667 | -383,771 | -2,686,397 | -18,804,779 | -131,633,453 |
