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 425,054,399, 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 | 425,054,399 | |
| -1 | -425,054,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,054,399.
Example:
1 x 425,054,399 = 425,054,399
and
-1 x -425,054,399 = 425,054,399
Notice both answers equal 425,054,399
With that explanation out of the way, let's continue. Next, we take the number 425,054,399 and divide it by 2:
425,054,399 ÷ 2 = 212,527,199.5
If the quotient is a whole number, then 2 and 212,527,199.5 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 | 425,054,399 | |
| -1 | -425,054,399 |
Now, we try dividing 425,054,399 by 3:
425,054,399 ÷ 3 = 141,684,799.6667
If the quotient is a whole number, then 3 and 141,684,799.6667 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 | 425,054,399 | |
| -1 | -425,054,399 |
Let's try dividing by 4:
425,054,399 ÷ 4 = 106,263,599.75
If the quotient is a whole number, then 4 and 106,263,599.75 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 | 425,054,399 | |
| -1 | 425,054,399 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 73 | 77 | 511 | 803 | 5,621 | 75,619 | 529,333 | 831,809 | 5,520,187 | 5,822,663 | 38,641,309 | 60,722,057 | 425,054,399 |
| -1 | -7 | -11 | -73 | -77 | -511 | -803 | -5,621 | -75,619 | -529,333 | -831,809 | -5,520,187 | -5,822,663 | -38,641,309 | -60,722,057 | -425,054,399 |
