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 5,145,713, 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 | 5,145,713 | |
| -1 | -5,145,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,145,713.
Example:
1 x 5,145,713 = 5,145,713
and
-1 x -5,145,713 = 5,145,713
Notice both answers equal 5,145,713
With that explanation out of the way, let's continue. Next, we take the number 5,145,713 and divide it by 2:
5,145,713 ÷ 2 = 2,572,856.5
If the quotient is a whole number, then 2 and 2,572,856.5 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 | 5,145,713 | |
| -1 | -5,145,713 |
Now, we try dividing 5,145,713 by 3:
5,145,713 ÷ 3 = 1,715,237.6667
If the quotient is a whole number, then 3 and 1,715,237.6667 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 | 5,145,713 | |
| -1 | -5,145,713 |
Let's try dividing by 4:
5,145,713 ÷ 4 = 1,286,428.25
If the quotient is a whole number, then 4 and 1,286,428.25 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 | 5,145,713 | |
| -1 | 5,145,713 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 89 | 179 | 323 | 1,513 | 1,691 | 3,043 | 3,401 | 15,931 | 28,747 | 57,817 | 270,827 | 302,689 | 5,145,713 |
| -1 | -17 | -19 | -89 | -179 | -323 | -1,513 | -1,691 | -3,043 | -3,401 | -15,931 | -28,747 | -57,817 | -270,827 | -302,689 | -5,145,713 |
