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 425,213,131, 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 | 425,213,131 | |
| -1 | -425,213,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,213,131.
Example:
1 x 425,213,131 = 425,213,131
and
-1 x -425,213,131 = 425,213,131
Notice both answers equal 425,213,131
With that explanation out of the way, let's continue. Next, we take the number 425,213,131 and divide it by 2:
425,213,131 ÷ 2 = 212,606,565.5
If the quotient is a whole number, then 2 and 212,606,565.5 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 | 425,213,131 | |
| -1 | -425,213,131 |
Now, we try dividing 425,213,131 by 3:
425,213,131 ÷ 3 = 141,737,710.3333
If the quotient is a whole number, then 3 and 141,737,710.3333 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 | 425,213,131 | |
| -1 | -425,213,131 |
Let's try dividing by 4:
425,213,131 ÷ 4 = 106,303,282.75
If the quotient is a whole number, then 4 and 106,303,282.75 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 | 425,213,131 | |
| -1 | 425,213,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 101 | 151 | 569 | 707 | 1,057 | 3,983 | 4,949 | 7,399 | 15,251 | 27,881 | 57,469 | 85,919 | 106,757 | 402,283 | 601,433 | 747,299 | 2,815,981 | 4,210,031 | 8,677,819 | 60,744,733 | 425,213,131 |
| -1 | -7 | -49 | -101 | -151 | -569 | -707 | -1,057 | -3,983 | -4,949 | -7,399 | -15,251 | -27,881 | -57,469 | -85,919 | -106,757 | -402,283 | -601,433 | -747,299 | -2,815,981 | -4,210,031 | -8,677,819 | -60,744,733 | -425,213,131 |
