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 615,043, 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 | 615,043 | |
| -1 | -615,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 615,043.
Example:
1 x 615,043 = 615,043
and
-1 x -615,043 = 615,043
Notice both answers equal 615,043
With that explanation out of the way, let's continue. Next, we take the number 615,043 and divide it by 2:
615,043 ÷ 2 = 307,521.5
If the quotient is a whole number, then 2 and 307,521.5 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 | 615,043 | |
| -1 | -615,043 |
Now, we try dividing 615,043 by 3:
615,043 ÷ 3 = 205,014.3333
If the quotient is a whole number, then 3 and 205,014.3333 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 | 615,043 | |
| -1 | -615,043 |
Let's try dividing by 4:
615,043 ÷ 4 = 153,760.75
If the quotient is a whole number, then 4 and 153,760.75 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 | 615,043 | |
| -1 | 615,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 23 | 121 | 143 | 187 | 221 | 253 | 299 | 391 | 1,573 | 2,057 | 2,431 | 2,783 | 3,289 | 4,301 | 5,083 | 26,741 | 36,179 | 47,311 | 55,913 | 615,043 |
| -1 | -11 | -13 | -17 | -23 | -121 | -143 | -187 | -221 | -253 | -299 | -391 | -1,573 | -2,057 | -2,431 | -2,783 | -3,289 | -4,301 | -5,083 | -26,741 | -36,179 | -47,311 | -55,913 | -615,043 |
