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 43,423,405, 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 | 43,423,405 | |
| -1 | -43,423,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,423,405.
Example:
1 x 43,423,405 = 43,423,405
and
-1 x -43,423,405 = 43,423,405
Notice both answers equal 43,423,405
With that explanation out of the way, let's continue. Next, we take the number 43,423,405 and divide it by 2:
43,423,405 ÷ 2 = 21,711,702.5
If the quotient is a whole number, then 2 and 21,711,702.5 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 | 43,423,405 | |
| -1 | -43,423,405 |
Now, we try dividing 43,423,405 by 3:
43,423,405 ÷ 3 = 14,474,468.3333
If the quotient is a whole number, then 3 and 14,474,468.3333 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 | 43,423,405 | |
| -1 | -43,423,405 |
Let's try dividing by 4:
43,423,405 ÷ 4 = 10,855,851.25
If the quotient is a whole number, then 4 and 10,855,851.25 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 | 43,423,405 | |
| -1 | 43,423,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 433 | 647 | 2,165 | 3,235 | 13,423 | 20,057 | 67,115 | 100,285 | 280,151 | 1,400,755 | 8,684,681 | 43,423,405 |
| -1 | -5 | -31 | -155 | -433 | -647 | -2,165 | -3,235 | -13,423 | -20,057 | -67,115 | -100,285 | -280,151 | -1,400,755 | -8,684,681 | -43,423,405 |
