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 5,156,393, 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 | 5,156,393 | |
| -1 | -5,156,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,156,393.
Example:
1 x 5,156,393 = 5,156,393
and
-1 x -5,156,393 = 5,156,393
Notice both answers equal 5,156,393
With that explanation out of the way, let's continue. Next, we take the number 5,156,393 and divide it by 2:
5,156,393 ÷ 2 = 2,578,196.5
If the quotient is a whole number, then 2 and 2,578,196.5 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 | 5,156,393 | |
| -1 | -5,156,393 |
Now, we try dividing 5,156,393 by 3:
5,156,393 ÷ 3 = 1,718,797.6667
If the quotient is a whole number, then 3 and 1,718,797.6667 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 | 5,156,393 | |
| -1 | -5,156,393 |
Let's try dividing by 4:
5,156,393 ÷ 4 = 1,289,098.25
If the quotient is a whole number, then 4 and 1,289,098.25 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 | 5,156,393 | |
| -1 | 5,156,393 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 89 | 229 | 253 | 979 | 2,047 | 2,519 | 5,267 | 20,381 | 22,517 | 57,937 | 224,191 | 468,763 | 5,156,393 |
| -1 | -11 | -23 | -89 | -229 | -253 | -979 | -2,047 | -2,519 | -5,267 | -20,381 | -22,517 | -57,937 | -224,191 | -468,763 | -5,156,393 |
