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 401,110,045, 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 | 401,110,045 | |
| -1 | -401,110,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,110,045.
Example:
1 x 401,110,045 = 401,110,045
and
-1 x -401,110,045 = 401,110,045
Notice both answers equal 401,110,045
With that explanation out of the way, let's continue. Next, we take the number 401,110,045 and divide it by 2:
401,110,045 ÷ 2 = 200,555,022.5
If the quotient is a whole number, then 2 and 200,555,022.5 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 | 401,110,045 | |
| -1 | -401,110,045 |
Now, we try dividing 401,110,045 by 3:
401,110,045 ÷ 3 = 133,703,348.3333
If the quotient is a whole number, then 3 and 133,703,348.3333 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 | 401,110,045 | |
| -1 | -401,110,045 |
Let's try dividing by 4:
401,110,045 ÷ 4 = 100,277,511.25
If the quotient is a whole number, then 4 and 100,277,511.25 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 | 401,110,045 | |
| -1 | 401,110,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 603,173 | 3,015,865 | 4,222,211 | 11,460,287 | 21,111,055 | 57,301,435 | 80,222,009 | 401,110,045 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -603,173 | -3,015,865 | -4,222,211 | -11,460,287 | -21,111,055 | -57,301,435 | -80,222,009 | -401,110,045 |
