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 425,314,099, 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 | 425,314,099 | |
| -1 | -425,314,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,314,099.
Example:
1 x 425,314,099 = 425,314,099
and
-1 x -425,314,099 = 425,314,099
Notice both answers equal 425,314,099
With that explanation out of the way, let's continue. Next, we take the number 425,314,099 and divide it by 2:
425,314,099 ÷ 2 = 212,657,049.5
If the quotient is a whole number, then 2 and 212,657,049.5 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 | 425,314,099 | |
| -1 | -425,314,099 |
Now, we try dividing 425,314,099 by 3:
425,314,099 ÷ 3 = 141,771,366.3333
If the quotient is a whole number, then 3 and 141,771,366.3333 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 | 425,314,099 | |
| -1 | -425,314,099 |
Let's try dividing by 4:
425,314,099 ÷ 4 = 106,328,524.75
If the quotient is a whole number, then 4 and 106,328,524.75 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 | 425,314,099 | |
| -1 | 425,314,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 157 | 173 | 1,099 | 1,211 | 2,237 | 15,659 | 27,161 | 190,127 | 351,209 | 387,001 | 2,458,463 | 2,709,007 | 60,759,157 | 425,314,099 |
| -1 | -7 | -157 | -173 | -1,099 | -1,211 | -2,237 | -15,659 | -27,161 | -190,127 | -351,209 | -387,001 | -2,458,463 | -2,709,007 | -60,759,157 | -425,314,099 |
