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 5,315,723, 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 | 5,315,723 | |
| -1 | -5,315,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,315,723.
Example:
1 x 5,315,723 = 5,315,723
and
-1 x -5,315,723 = 5,315,723
Notice both answers equal 5,315,723
With that explanation out of the way, let's continue. Next, we take the number 5,315,723 and divide it by 2:
5,315,723 ÷ 2 = 2,657,861.5
If the quotient is a whole number, then 2 and 2,657,861.5 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 | 5,315,723 | |
| -1 | -5,315,723 |
Now, we try dividing 5,315,723 by 3:
5,315,723 ÷ 3 = 1,771,907.6667
If the quotient is a whole number, then 3 and 1,771,907.6667 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 | 5,315,723 | |
| -1 | -5,315,723 |
Let's try dividing by 4:
5,315,723 ÷ 4 = 1,328,930.75
If the quotient is a whole number, then 4 and 1,328,930.75 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 | 5,315,723 | |
| -1 | 5,315,723 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 61 | 211 | 413 | 427 | 1,477 | 3,599 | 12,449 | 12,871 | 25,193 | 87,143 | 90,097 | 759,389 | 5,315,723 |
| -1 | -7 | -59 | -61 | -211 | -413 | -427 | -1,477 | -3,599 | -12,449 | -12,871 | -25,193 | -87,143 | -90,097 | -759,389 | -5,315,723 |
