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 401,734,345, 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 | 401,734,345 | |
| -1 | -401,734,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,734,345.
Example:
1 x 401,734,345 = 401,734,345
and
-1 x -401,734,345 = 401,734,345
Notice both answers equal 401,734,345
With that explanation out of the way, let's continue. Next, we take the number 401,734,345 and divide it by 2:
401,734,345 ÷ 2 = 200,867,172.5
If the quotient is a whole number, then 2 and 200,867,172.5 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 | 401,734,345 | |
| -1 | -401,734,345 |
Now, we try dividing 401,734,345 by 3:
401,734,345 ÷ 3 = 133,911,448.3333
If the quotient is a whole number, then 3 and 133,911,448.3333 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 | 401,734,345 | |
| -1 | -401,734,345 |
Let's try dividing by 4:
401,734,345 ÷ 4 = 100,433,586.25
If the quotient is a whole number, then 4 and 100,433,586.25 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 | 401,734,345 | |
| -1 | 401,734,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 2,479 | 12,395 | 32,411 | 162,055 | 1,199,207 | 2,171,537 | 5,996,035 | 10,857,685 | 80,346,869 | 401,734,345 |
| -1 | -5 | -37 | -67 | -185 | -335 | -2,479 | -12,395 | -32,411 | -162,055 | -1,199,207 | -2,171,537 | -5,996,035 | -10,857,685 | -80,346,869 | -401,734,345 |
