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 401,403,235, 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 | 401,403,235 | |
| -1 | -401,403,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,403,235.
Example:
1 x 401,403,235 = 401,403,235
and
-1 x -401,403,235 = 401,403,235
Notice both answers equal 401,403,235
With that explanation out of the way, let's continue. Next, we take the number 401,403,235 and divide it by 2:
401,403,235 ÷ 2 = 200,701,617.5
If the quotient is a whole number, then 2 and 200,701,617.5 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 | 401,403,235 | |
| -1 | -401,403,235 |
Now, we try dividing 401,403,235 by 3:
401,403,235 ÷ 3 = 133,801,078.3333
If the quotient is a whole number, then 3 and 133,801,078.3333 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 | 401,403,235 | |
| -1 | -401,403,235 |
Let's try dividing by 4:
401,403,235 ÷ 4 = 100,350,808.75
If the quotient is a whole number, then 4 and 100,350,808.75 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 | 401,403,235 | |
| -1 | 401,403,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 211 | 1,055 | 3,587 | 17,935 | 22,381 | 111,905 | 380,477 | 1,902,385 | 4,722,391 | 23,611,955 | 80,280,647 | 401,403,235 |
| -1 | -5 | -17 | -85 | -211 | -1,055 | -3,587 | -17,935 | -22,381 | -111,905 | -380,477 | -1,902,385 | -4,722,391 | -23,611,955 | -80,280,647 | -401,403,235 |
