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 425,350,145, 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 | 425,350,145 | |
| -1 | -425,350,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,350,145.
Example:
1 x 425,350,145 = 425,350,145
and
-1 x -425,350,145 = 425,350,145
Notice both answers equal 425,350,145
With that explanation out of the way, let's continue. Next, we take the number 425,350,145 and divide it by 2:
425,350,145 ÷ 2 = 212,675,072.5
If the quotient is a whole number, then 2 and 212,675,072.5 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 | 425,350,145 | |
| -1 | -425,350,145 |
Now, we try dividing 425,350,145 by 3:
425,350,145 ÷ 3 = 141,783,381.6667
If the quotient is a whole number, then 3 and 141,783,381.6667 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 | 425,350,145 | |
| -1 | -425,350,145 |
Let's try dividing by 4:
425,350,145 ÷ 4 = 106,337,536.25
If the quotient is a whole number, then 4 and 106,337,536.25 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 | 425,350,145 | |
| -1 | 425,350,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 1,177 | 5,885 | 72,277 | 361,385 | 795,047 | 3,975,235 | 7,733,639 | 38,668,195 | 85,070,029 | 425,350,145 |
| -1 | -5 | -11 | -55 | -107 | -535 | -1,177 | -5,885 | -72,277 | -361,385 | -795,047 | -3,975,235 | -7,733,639 | -38,668,195 | -85,070,029 | -425,350,145 |
