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 402,452,459, 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 | 402,452,459 | |
| -1 | -402,452,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 402,452,459.
Example:
1 x 402,452,459 = 402,452,459
and
-1 x -402,452,459 = 402,452,459
Notice both answers equal 402,452,459
With that explanation out of the way, let's continue. Next, we take the number 402,452,459 and divide it by 2:
402,452,459 ÷ 2 = 201,226,229.5
If the quotient is a whole number, then 2 and 201,226,229.5 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 | 402,452,459 | |
| -1 | -402,452,459 |
Now, we try dividing 402,452,459 by 3:
402,452,459 ÷ 3 = 134,150,819.6667
If the quotient is a whole number, then 3 and 134,150,819.6667 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 | 402,452,459 | |
| -1 | -402,452,459 |
Let's try dividing by 4:
402,452,459 ÷ 4 = 100,613,114.75
If the quotient is a whole number, then 4 and 100,613,114.75 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 | 402,452,459 | |
| -1 | 402,452,459 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 127 | 667 | 2,921 | 3,683 | 4,751 | 84,709 | 109,273 | 137,779 | 603,377 | 3,168,917 | 13,877,671 | 17,497,933 | 402,452,459 |
| -1 | -23 | -29 | -127 | -667 | -2,921 | -3,683 | -4,751 | -84,709 | -109,273 | -137,779 | -603,377 | -3,168,917 | -13,877,671 | -17,497,933 | -402,452,459 |
