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 147,438,755, 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 | 147,438,755 | |
| -1 | -147,438,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,438,755.
Example:
1 x 147,438,755 = 147,438,755
and
-1 x -147,438,755 = 147,438,755
Notice both answers equal 147,438,755
With that explanation out of the way, let's continue. Next, we take the number 147,438,755 and divide it by 2:
147,438,755 ÷ 2 = 73,719,377.5
If the quotient is a whole number, then 2 and 73,719,377.5 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 | 147,438,755 | |
| -1 | -147,438,755 |
Now, we try dividing 147,438,755 by 3:
147,438,755 ÷ 3 = 49,146,251.6667
If the quotient is a whole number, then 3 and 49,146,251.6667 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 | 147,438,755 | |
| -1 | -147,438,755 |
Let's try dividing by 4:
147,438,755 ÷ 4 = 36,859,688.75
If the quotient is a whole number, then 4 and 36,859,688.75 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 | 147,438,755 | |
| -1 | 147,438,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 283 | 1,415 | 3,593 | 8,207 | 17,965 | 41,035 | 104,197 | 520,985 | 1,016,819 | 5,084,095 | 29,487,751 | 147,438,755 |
| -1 | -5 | -29 | -145 | -283 | -1,415 | -3,593 | -8,207 | -17,965 | -41,035 | -104,197 | -520,985 | -1,016,819 | -5,084,095 | -29,487,751 | -147,438,755 |
