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 587,248,165, 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 | 587,248,165 | |
| -1 | -587,248,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 587,248,165.
Example:
1 x 587,248,165 = 587,248,165
and
-1 x -587,248,165 = 587,248,165
Notice both answers equal 587,248,165
With that explanation out of the way, let's continue. Next, we take the number 587,248,165 and divide it by 2:
587,248,165 ÷ 2 = 293,624,082.5
If the quotient is a whole number, then 2 and 293,624,082.5 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 | 587,248,165 | |
| -1 | -587,248,165 |
Now, we try dividing 587,248,165 by 3:
587,248,165 ÷ 3 = 195,749,388.3333
If the quotient is a whole number, then 3 and 195,749,388.3333 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 | 587,248,165 | |
| -1 | -587,248,165 |
Let's try dividing by 4:
587,248,165 ÷ 4 = 146,812,041.25
If the quotient is a whole number, then 4 and 146,812,041.25 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 | 587,248,165 | |
| -1 | 587,248,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 905 | 1,267 | 6,335 | 92,699 | 463,495 | 648,893 | 3,244,465 | 16,778,519 | 83,892,595 | 117,449,633 | 587,248,165 |
| -1 | -5 | -7 | -35 | -181 | -905 | -1,267 | -6,335 | -92,699 | -463,495 | -648,893 | -3,244,465 | -16,778,519 | -83,892,595 | -117,449,633 | -587,248,165 |
