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 549,684,515, 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 | 549,684,515 | |
| -1 | -549,684,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 549,684,515.
Example:
1 x 549,684,515 = 549,684,515
and
-1 x -549,684,515 = 549,684,515
Notice both answers equal 549,684,515
With that explanation out of the way, let's continue. Next, we take the number 549,684,515 and divide it by 2:
549,684,515 ÷ 2 = 274,842,257.5
If the quotient is a whole number, then 2 and 274,842,257.5 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 | 549,684,515 | |
| -1 | -549,684,515 |
Now, we try dividing 549,684,515 by 3:
549,684,515 ÷ 3 = 183,228,171.6667
If the quotient is a whole number, then 3 and 183,228,171.6667 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 | 549,684,515 | |
| -1 | -549,684,515 |
Let's try dividing by 4:
549,684,515 ÷ 4 = 137,421,128.75
If the quotient is a whole number, then 4 and 137,421,128.75 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 | 549,684,515 | |
| -1 | 549,684,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 131 | 415 | 655 | 10,111 | 10,873 | 50,555 | 54,365 | 839,213 | 1,324,541 | 4,196,065 | 6,622,705 | 109,936,903 | 549,684,515 |
| -1 | -5 | -83 | -131 | -415 | -655 | -10,111 | -10,873 | -50,555 | -54,365 | -839,213 | -1,324,541 | -4,196,065 | -6,622,705 | -109,936,903 | -549,684,515 |
