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 425,112,205, 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 | 425,112,205 | |
| -1 | -425,112,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,112,205.
Example:
1 x 425,112,205 = 425,112,205
and
-1 x -425,112,205 = 425,112,205
Notice both answers equal 425,112,205
With that explanation out of the way, let's continue. Next, we take the number 425,112,205 and divide it by 2:
425,112,205 ÷ 2 = 212,556,102.5
If the quotient is a whole number, then 2 and 212,556,102.5 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 | 425,112,205 | |
| -1 | -425,112,205 |
Now, we try dividing 425,112,205 by 3:
425,112,205 ÷ 3 = 141,704,068.3333
If the quotient is a whole number, then 3 and 141,704,068.3333 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 | 425,112,205 | |
| -1 | -425,112,205 |
Let's try dividing by 4:
425,112,205 ÷ 4 = 106,278,051.25
If the quotient is a whole number, then 4 and 106,278,051.25 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 | 425,112,205 | |
| -1 | 425,112,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 229,171 | 1,145,855 | 1,604,197 | 8,020,985 | 12,146,063 | 60,730,315 | 85,022,441 | 425,112,205 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -229,171 | -1,145,855 | -1,604,197 | -8,020,985 | -12,146,063 | -60,730,315 | -85,022,441 | -425,112,205 |
