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 5,425,651, 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 | 5,425,651 | |
| -1 | -5,425,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,425,651.
Example:
1 x 5,425,651 = 5,425,651
and
-1 x -5,425,651 = 5,425,651
Notice both answers equal 5,425,651
With that explanation out of the way, let's continue. Next, we take the number 5,425,651 and divide it by 2:
5,425,651 ÷ 2 = 2,712,825.5
If the quotient is a whole number, then 2 and 2,712,825.5 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 | 5,425,651 | |
| -1 | -5,425,651 |
Now, we try dividing 5,425,651 by 3:
5,425,651 ÷ 3 = 1,808,550.3333
If the quotient is a whole number, then 3 and 1,808,550.3333 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 | 5,425,651 | |
| -1 | -5,425,651 |
Let's try dividing by 4:
5,425,651 ÷ 4 = 1,356,412.75
If the quotient is a whole number, then 4 and 1,356,412.75 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 | 5,425,651 | |
| -1 | 5,425,651 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,273 | 2,387 | 15,911 | 25,003 | 70,463 | 175,021 | 493,241 | 775,093 | 5,425,651 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,273 | -2,387 | -15,911 | -25,003 | -70,463 | -175,021 | -493,241 | -775,093 | -5,425,651 |
