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 435,316,145, 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 | 435,316,145 | |
| -1 | -435,316,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 435,316,145.
Example:
1 x 435,316,145 = 435,316,145
and
-1 x -435,316,145 = 435,316,145
Notice both answers equal 435,316,145
With that explanation out of the way, let's continue. Next, we take the number 435,316,145 and divide it by 2:
435,316,145 ÷ 2 = 217,658,072.5
If the quotient is a whole number, then 2 and 217,658,072.5 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 | 435,316,145 | |
| -1 | -435,316,145 |
Now, we try dividing 435,316,145 by 3:
435,316,145 ÷ 3 = 145,105,381.6667
If the quotient is a whole number, then 3 and 145,105,381.6667 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 | 435,316,145 | |
| -1 | -435,316,145 |
Let's try dividing by 4:
435,316,145 ÷ 4 = 108,829,036.25
If the quotient is a whole number, then 4 and 108,829,036.25 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 | 435,316,145 | |
| -1 | 435,316,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 937 | 4,685 | 8,447 | 10,307 | 42,235 | 51,535 | 92,917 | 464,585 | 7,914,839 | 39,574,195 | 87,063,229 | 435,316,145 |
| -1 | -5 | -11 | -55 | -937 | -4,685 | -8,447 | -10,307 | -42,235 | -51,535 | -92,917 | -464,585 | -7,914,839 | -39,574,195 | -87,063,229 | -435,316,145 |
