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 401,315,035, 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 | 401,315,035 | |
| -1 | -401,315,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,315,035.
Example:
1 x 401,315,035 = 401,315,035
and
-1 x -401,315,035 = 401,315,035
Notice both answers equal 401,315,035
With that explanation out of the way, let's continue. Next, we take the number 401,315,035 and divide it by 2:
401,315,035 ÷ 2 = 200,657,517.5
If the quotient is a whole number, then 2 and 200,657,517.5 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 | 401,315,035 | |
| -1 | -401,315,035 |
Now, we try dividing 401,315,035 by 3:
401,315,035 ÷ 3 = 133,771,678.3333
If the quotient is a whole number, then 3 and 133,771,678.3333 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 | 401,315,035 | |
| -1 | -401,315,035 |
Let's try dividing by 4:
401,315,035 ÷ 4 = 100,328,758.75
If the quotient is a whole number, then 4 and 100,328,758.75 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 | 401,315,035 | |
| -1 | 401,315,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 119,617 | 598,085 | 1,315,787 | 6,578,935 | 7,296,637 | 36,483,185 | 80,263,007 | 401,315,035 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -119,617 | -598,085 | -1,315,787 | -6,578,935 | -7,296,637 | -36,483,185 | -80,263,007 | -401,315,035 |
