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 5,515,315, 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 | 5,515,315 | |
| -1 | -5,515,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,515,315.
Example:
1 x 5,515,315 = 5,515,315
and
-1 x -5,515,315 = 5,515,315
Notice both answers equal 5,515,315
With that explanation out of the way, let's continue. Next, we take the number 5,515,315 and divide it by 2:
5,515,315 ÷ 2 = 2,757,657.5
If the quotient is a whole number, then 2 and 2,757,657.5 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 | 5,515,315 | |
| -1 | -5,515,315 |
Now, we try dividing 5,515,315 by 3:
5,515,315 ÷ 3 = 1,838,438.3333
If the quotient is a whole number, then 3 and 1,838,438.3333 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 | 5,515,315 | |
| -1 | -5,515,315 |
Let's try dividing by 4:
5,515,315 ÷ 4 = 1,378,828.75
If the quotient is a whole number, then 4 and 1,378,828.75 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 | 5,515,315 | |
| -1 | 5,515,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 107 | 169 | 305 | 535 | 793 | 845 | 1,391 | 3,965 | 6,527 | 6,955 | 10,309 | 18,083 | 32,635 | 51,545 | 84,851 | 90,415 | 424,255 | 1,103,063 | 5,515,315 |
| -1 | -5 | -13 | -61 | -65 | -107 | -169 | -305 | -535 | -793 | -845 | -1,391 | -3,965 | -6,527 | -6,955 | -10,309 | -18,083 | -32,635 | -51,545 | -84,851 | -90,415 | -424,255 | -1,103,063 | -5,515,315 |
