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 549,684,505, 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 | 549,684,505 | |
| -1 | -549,684,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 549,684,505.
Example:
1 x 549,684,505 = 549,684,505
and
-1 x -549,684,505 = 549,684,505
Notice both answers equal 549,684,505
With that explanation out of the way, let's continue. Next, we take the number 549,684,505 and divide it by 2:
549,684,505 ÷ 2 = 274,842,252.5
If the quotient is a whole number, then 2 and 274,842,252.5 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 | 549,684,505 | |
| -1 | -549,684,505 |
Now, we try dividing 549,684,505 by 3:
549,684,505 ÷ 3 = 183,228,168.3333
If the quotient is a whole number, then 3 and 183,228,168.3333 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 | 549,684,505 | |
| -1 | -549,684,505 |
Let's try dividing by 4:
549,684,505 ÷ 4 = 137,421,126.25
If the quotient is a whole number, then 4 and 137,421,126.25 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 | 549,684,505 | |
| -1 | 549,684,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 373 | 1,865 | 6,271 | 17,531 | 31,355 | 87,655 | 294,737 | 1,473,685 | 2,339,083 | 11,695,415 | 109,936,901 | 549,684,505 |
| -1 | -5 | -47 | -235 | -373 | -1,865 | -6,271 | -17,531 | -31,355 | -87,655 | -294,737 | -1,473,685 | -2,339,083 | -11,695,415 | -109,936,901 | -549,684,505 |
