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 704,147,315, 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 | 704,147,315 | |
| -1 | -704,147,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 704,147,315.
Example:
1 x 704,147,315 = 704,147,315
and
-1 x -704,147,315 = 704,147,315
Notice both answers equal 704,147,315
With that explanation out of the way, let's continue. Next, we take the number 704,147,315 and divide it by 2:
704,147,315 ÷ 2 = 352,073,657.5
If the quotient is a whole number, then 2 and 352,073,657.5 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 | 704,147,315 | |
| -1 | -704,147,315 |
Now, we try dividing 704,147,315 by 3:
704,147,315 ÷ 3 = 234,715,771.6667
If the quotient is a whole number, then 3 and 234,715,771.6667 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 | 704,147,315 | |
| -1 | -704,147,315 |
Let's try dividing by 4:
704,147,315 ÷ 4 = 176,036,828.75
If the quotient is a whole number, then 4 and 176,036,828.75 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 | 704,147,315 | |
| -1 | 704,147,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 607 | 3,035 | 11,533 | 12,211 | 57,665 | 61,055 | 232,009 | 1,160,045 | 7,412,077 | 37,060,385 | 140,829,463 | 704,147,315 |
| -1 | -5 | -19 | -95 | -607 | -3,035 | -11,533 | -12,211 | -57,665 | -61,055 | -232,009 | -1,160,045 | -7,412,077 | -37,060,385 | -140,829,463 | -704,147,315 |
