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 146,732,287, 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 | 146,732,287 | |
| -1 | -146,732,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,732,287.
Example:
1 x 146,732,287 = 146,732,287
and
-1 x -146,732,287 = 146,732,287
Notice both answers equal 146,732,287
With that explanation out of the way, let's continue. Next, we take the number 146,732,287 and divide it by 2:
146,732,287 ÷ 2 = 73,366,143.5
If the quotient is a whole number, then 2 and 73,366,143.5 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 | 146,732,287 | |
| -1 | -146,732,287 |
Now, we try dividing 146,732,287 by 3:
146,732,287 ÷ 3 = 48,910,762.3333
If the quotient is a whole number, then 3 and 48,910,762.3333 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 | 146,732,287 | |
| -1 | -146,732,287 |
Let's try dividing by 4:
146,732,287 ÷ 4 = 36,683,071.75
If the quotient is a whole number, then 4 and 36,683,071.75 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 | 146,732,287 | |
| -1 | 146,732,287 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 151 | 221 | 1,963 | 2,567 | 4,397 | 33,371 | 57,161 | 74,749 | 663,947 | 971,737 | 8,631,311 | 11,287,099 | 146,732,287 |
| -1 | -13 | -17 | -151 | -221 | -1,963 | -2,567 | -4,397 | -33,371 | -57,161 | -74,749 | -663,947 | -971,737 | -8,631,311 | -11,287,099 | -146,732,287 |
