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 435,404,207, 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 | 435,404,207 | |
| -1 | -435,404,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 435,404,207.
Example:
1 x 435,404,207 = 435,404,207
and
-1 x -435,404,207 = 435,404,207
Notice both answers equal 435,404,207
With that explanation out of the way, let's continue. Next, we take the number 435,404,207 and divide it by 2:
435,404,207 ÷ 2 = 217,702,103.5
If the quotient is a whole number, then 2 and 217,702,103.5 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 | 435,404,207 | |
| -1 | -435,404,207 |
Now, we try dividing 435,404,207 by 3:
435,404,207 ÷ 3 = 145,134,735.6667
If the quotient is a whole number, then 3 and 145,134,735.6667 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 | 435,404,207 | |
| -1 | -435,404,207 |
Let's try dividing by 4:
435,404,207 ÷ 4 = 108,851,051.75
If the quotient is a whole number, then 4 and 108,851,051.75 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 | 435,404,207 | |
| -1 | 435,404,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 269 | 1,883 | 7,459 | 8,339 | 52,213 | 58,373 | 231,229 | 1,618,603 | 2,006,471 | 14,045,297 | 62,200,601 | 435,404,207 |
| -1 | -7 | -31 | -217 | -269 | -1,883 | -7,459 | -8,339 | -52,213 | -58,373 | -231,229 | -1,618,603 | -2,006,471 | -14,045,297 | -62,200,601 | -435,404,207 |
