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 146,545,013, 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 | 146,545,013 | |
| -1 | -146,545,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,545,013.
Example:
1 x 146,545,013 = 146,545,013
and
-1 x -146,545,013 = 146,545,013
Notice both answers equal 146,545,013
With that explanation out of the way, let's continue. Next, we take the number 146,545,013 and divide it by 2:
146,545,013 ÷ 2 = 73,272,506.5
If the quotient is a whole number, then 2 and 73,272,506.5 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 | 146,545,013 | |
| -1 | -146,545,013 |
Now, we try dividing 146,545,013 by 3:
146,545,013 ÷ 3 = 48,848,337.6667
If the quotient is a whole number, then 3 and 48,848,337.6667 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 | 146,545,013 | |
| -1 | -146,545,013 |
Let's try dividing by 4:
146,545,013 ÷ 4 = 36,636,253.25
If the quotient is a whole number, then 4 and 36,636,253.25 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 | 146,545,013 | |
| -1 | 146,545,013 |
If you did it right, you will end up with this table:
| 1 | 47 | 67 | 173 | 269 | 3,149 | 8,131 | 11,591 | 12,643 | 18,023 | 46,537 | 544,777 | 847,081 | 2,187,239 | 3,117,979 | 146,545,013 |
| -1 | -47 | -67 | -173 | -269 | -3,149 | -8,131 | -11,591 | -12,643 | -18,023 | -46,537 | -544,777 | -847,081 | -2,187,239 | -3,117,979 | -146,545,013 |
