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 5,151,355, 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 | 5,151,355 | |
| -1 | -5,151,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,151,355.
Example:
1 x 5,151,355 = 5,151,355
and
-1 x -5,151,355 = 5,151,355
Notice both answers equal 5,151,355
With that explanation out of the way, let's continue. Next, we take the number 5,151,355 and divide it by 2:
5,151,355 ÷ 2 = 2,575,677.5
If the quotient is a whole number, then 2 and 2,575,677.5 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 | 5,151,355 | |
| -1 | -5,151,355 |
Now, we try dividing 5,151,355 by 3:
5,151,355 ÷ 3 = 1,717,118.3333
If the quotient is a whole number, then 3 and 1,717,118.3333 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 | 5,151,355 | |
| -1 | -5,151,355 |
Let's try dividing by 4:
5,151,355 ÷ 4 = 1,287,838.75
If the quotient is a whole number, then 4 and 1,287,838.75 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 | 5,151,355 | |
| -1 | 5,151,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 229 | 409 | 1,145 | 2,045 | 2,519 | 4,499 | 12,595 | 22,495 | 93,661 | 468,305 | 1,030,271 | 5,151,355 |
| -1 | -5 | -11 | -55 | -229 | -409 | -1,145 | -2,045 | -2,519 | -4,499 | -12,595 | -22,495 | -93,661 | -468,305 | -1,030,271 | -5,151,355 |
