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 131,244,053, 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 | 131,244,053 | |
| -1 | -131,244,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,244,053.
Example:
1 x 131,244,053 = 131,244,053
and
-1 x -131,244,053 = 131,244,053
Notice both answers equal 131,244,053
With that explanation out of the way, let's continue. Next, we take the number 131,244,053 and divide it by 2:
131,244,053 ÷ 2 = 65,622,026.5
If the quotient is a whole number, then 2 and 65,622,026.5 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 | 131,244,053 | |
| -1 | -131,244,053 |
Now, we try dividing 131,244,053 by 3:
131,244,053 ÷ 3 = 43,748,017.6667
If the quotient is a whole number, then 3 and 43,748,017.6667 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 | 131,244,053 | |
| -1 | -131,244,053 |
Let's try dividing by 4:
131,244,053 ÷ 4 = 32,811,013.25
If the quotient is a whole number, then 4 and 32,811,013.25 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 | 131,244,053 | |
| -1 | 131,244,053 |
If you did it right, you will end up with this table:
| 1 | 29 | 131 | 179 | 193 | 3,799 | 5,191 | 5,597 | 23,449 | 25,283 | 34,547 | 680,021 | 733,207 | 1,001,863 | 4,525,657 | 131,244,053 |
| -1 | -29 | -131 | -179 | -193 | -3,799 | -5,191 | -5,597 | -23,449 | -25,283 | -34,547 | -680,021 | -733,207 | -1,001,863 | -4,525,657 | -131,244,053 |
