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 132,453,013, 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 | 132,453,013 | |
| -1 | -132,453,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,453,013.
Example:
1 x 132,453,013 = 132,453,013
and
-1 x -132,453,013 = 132,453,013
Notice both answers equal 132,453,013
With that explanation out of the way, let's continue. Next, we take the number 132,453,013 and divide it by 2:
132,453,013 ÷ 2 = 66,226,506.5
If the quotient is a whole number, then 2 and 66,226,506.5 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 | 132,453,013 | |
| -1 | -132,453,013 |
Now, we try dividing 132,453,013 by 3:
132,453,013 ÷ 3 = 44,151,004.3333
If the quotient is a whole number, then 3 and 44,151,004.3333 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 | 132,453,013 | |
| -1 | -132,453,013 |
Let's try dividing by 4:
132,453,013 ÷ 4 = 33,113,253.25
If the quotient is a whole number, then 4 and 33,113,253.25 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 | 132,453,013 | |
| -1 | 132,453,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 121 | 353 | 443 | 847 | 2,471 | 3,101 | 3,883 | 4,873 | 27,181 | 34,111 | 42,713 | 53,603 | 156,379 | 298,991 | 375,221 | 1,094,653 | 1,720,169 | 12,041,183 | 18,921,859 | 132,453,013 |
| -1 | -7 | -11 | -77 | -121 | -353 | -443 | -847 | -2,471 | -3,101 | -3,883 | -4,873 | -27,181 | -34,111 | -42,713 | -53,603 | -156,379 | -298,991 | -375,221 | -1,094,653 | -1,720,169 | -12,041,183 | -18,921,859 | -132,453,013 |
