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 425,151,349, 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 | 425,151,349 | |
| -1 | -425,151,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,151,349.
Example:
1 x 425,151,349 = 425,151,349
and
-1 x -425,151,349 = 425,151,349
Notice both answers equal 425,151,349
With that explanation out of the way, let's continue. Next, we take the number 425,151,349 and divide it by 2:
425,151,349 ÷ 2 = 212,575,674.5
If the quotient is a whole number, then 2 and 212,575,674.5 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 | 425,151,349 | |
| -1 | -425,151,349 |
Now, we try dividing 425,151,349 by 3:
425,151,349 ÷ 3 = 141,717,116.3333
If the quotient is a whole number, then 3 and 141,717,116.3333 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 | 425,151,349 | |
| -1 | -425,151,349 |
Let's try dividing by 4:
425,151,349 ÷ 4 = 106,287,837.25
If the quotient is a whole number, then 4 and 106,287,837.25 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 | 425,151,349 | |
| -1 | 425,151,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 103 | 259 | 721 | 3,811 | 15,937 | 26,677 | 111,559 | 589,669 | 1,641,511 | 4,127,683 | 11,490,577 | 60,735,907 | 425,151,349 |
| -1 | -7 | -37 | -103 | -259 | -721 | -3,811 | -15,937 | -26,677 | -111,559 | -589,669 | -1,641,511 | -4,127,683 | -11,490,577 | -60,735,907 | -425,151,349 |
