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 403,012,445, 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 | 403,012,445 | |
| -1 | -403,012,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,012,445.
Example:
1 x 403,012,445 = 403,012,445
and
-1 x -403,012,445 = 403,012,445
Notice both answers equal 403,012,445
With that explanation out of the way, let's continue. Next, we take the number 403,012,445 and divide it by 2:
403,012,445 ÷ 2 = 201,506,222.5
If the quotient is a whole number, then 2 and 201,506,222.5 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 | 403,012,445 | |
| -1 | -403,012,445 |
Now, we try dividing 403,012,445 by 3:
403,012,445 ÷ 3 = 134,337,481.6667
If the quotient is a whole number, then 3 and 134,337,481.6667 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 | 403,012,445 | |
| -1 | -403,012,445 |
Let's try dividing by 4:
403,012,445 ÷ 4 = 100,753,111.25
If the quotient is a whole number, then 4 and 100,753,111.25 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 | 403,012,445 | |
| -1 | 403,012,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 2,473 | 2,963 | 12,365 | 14,815 | 27,203 | 32,593 | 136,015 | 162,965 | 7,327,499 | 36,637,495 | 80,602,489 | 403,012,445 |
| -1 | -5 | -11 | -55 | -2,473 | -2,963 | -12,365 | -14,815 | -27,203 | -32,593 | -136,015 | -162,965 | -7,327,499 | -36,637,495 | -80,602,489 | -403,012,445 |
