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 146,058,187, 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 | 146,058,187 | |
| -1 | -146,058,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,058,187.
Example:
1 x 146,058,187 = 146,058,187
and
-1 x -146,058,187 = 146,058,187
Notice both answers equal 146,058,187
With that explanation out of the way, let's continue. Next, we take the number 146,058,187 and divide it by 2:
146,058,187 ÷ 2 = 73,029,093.5
If the quotient is a whole number, then 2 and 73,029,093.5 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 | 146,058,187 | |
| -1 | -146,058,187 |
Now, we try dividing 146,058,187 by 3:
146,058,187 ÷ 3 = 48,686,062.3333
If the quotient is a whole number, then 3 and 48,686,062.3333 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 | 146,058,187 | |
| -1 | -146,058,187 |
Let's try dividing by 4:
146,058,187 ÷ 4 = 36,514,546.75
If the quotient is a whole number, then 4 and 36,514,546.75 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 | 146,058,187 | |
| -1 | 146,058,187 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 47 | 209 | 517 | 893 | 9,823 | 14,869 | 163,559 | 282,511 | 698,843 | 3,107,621 | 7,687,273 | 13,278,017 | 146,058,187 |
| -1 | -11 | -19 | -47 | -209 | -517 | -893 | -9,823 | -14,869 | -163,559 | -282,511 | -698,843 | -3,107,621 | -7,687,273 | -13,278,017 | -146,058,187 |
