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 147,312,055, 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 | 147,312,055 | |
| -1 | -147,312,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,312,055.
Example:
1 x 147,312,055 = 147,312,055
and
-1 x -147,312,055 = 147,312,055
Notice both answers equal 147,312,055
With that explanation out of the way, let's continue. Next, we take the number 147,312,055 and divide it by 2:
147,312,055 ÷ 2 = 73,656,027.5
If the quotient is a whole number, then 2 and 73,656,027.5 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 | 147,312,055 | |
| -1 | -147,312,055 |
Now, we try dividing 147,312,055 by 3:
147,312,055 ÷ 3 = 49,104,018.3333
If the quotient is a whole number, then 3 and 49,104,018.3333 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 | 147,312,055 | |
| -1 | -147,312,055 |
Let's try dividing by 4:
147,312,055 ÷ 4 = 36,828,013.75
If the quotient is a whole number, then 4 and 36,828,013.75 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 | 147,312,055 | |
| -1 | 147,312,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 121 | 187 | 605 | 935 | 2,057 | 10,285 | 14,323 | 71,615 | 157,553 | 243,491 | 787,765 | 1,217,455 | 1,733,083 | 2,678,401 | 8,665,415 | 13,392,005 | 29,462,411 | 147,312,055 |
| -1 | -5 | -11 | -17 | -55 | -85 | -121 | -187 | -605 | -935 | -2,057 | -10,285 | -14,323 | -71,615 | -157,553 | -243,491 | -787,765 | -1,217,455 | -1,733,083 | -2,678,401 | -8,665,415 | -13,392,005 | -29,462,411 | -147,312,055 |
