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 607,731,473, 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 | 607,731,473 | |
| -1 | -607,731,473 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 607,731,473.
Example:
1 x 607,731,473 = 607,731,473
and
-1 x -607,731,473 = 607,731,473
Notice both answers equal 607,731,473
With that explanation out of the way, let's continue. Next, we take the number 607,731,473 and divide it by 2:
607,731,473 ÷ 2 = 303,865,736.5
If the quotient is a whole number, then 2 and 303,865,736.5 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 | 607,731,473 | |
| -1 | -607,731,473 |
Now, we try dividing 607,731,473 by 3:
607,731,473 ÷ 3 = 202,577,157.6667
If the quotient is a whole number, then 3 and 202,577,157.6667 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 | 607,731,473 | |
| -1 | -607,731,473 |
Let's try dividing by 4:
607,731,473 ÷ 4 = 151,932,868.25
If the quotient is a whole number, then 4 and 151,932,868.25 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 | 607,731,473 | |
| -1 | 607,731,473 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 199 | 1,273 | 2,399 | 3,781 | 13,333 | 45,581 | 160,733 | 253,327 | 477,401 | 3,053,927 | 9,070,619 | 31,985,867 | 607,731,473 |
| -1 | -19 | -67 | -199 | -1,273 | -2,399 | -3,781 | -13,333 | -45,581 | -160,733 | -253,327 | -477,401 | -3,053,927 | -9,070,619 | -31,985,867 | -607,731,473 |
