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 43,001,315, 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 | 43,001,315 | |
| -1 | -43,001,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,001,315.
Example:
1 x 43,001,315 = 43,001,315
and
-1 x -43,001,315 = 43,001,315
Notice both answers equal 43,001,315
With that explanation out of the way, let's continue. Next, we take the number 43,001,315 and divide it by 2:
43,001,315 ÷ 2 = 21,500,657.5
If the quotient is a whole number, then 2 and 21,500,657.5 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 | 43,001,315 | |
| -1 | -43,001,315 |
Now, we try dividing 43,001,315 by 3:
43,001,315 ÷ 3 = 14,333,771.6667
If the quotient is a whole number, then 3 and 14,333,771.6667 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 | 43,001,315 | |
| -1 | -43,001,315 |
Let's try dividing by 4:
43,001,315 ÷ 4 = 10,750,328.75
If the quotient is a whole number, then 4 and 10,750,328.75 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 | 43,001,315 | |
| -1 | 43,001,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 1,165 | 1,631 | 5,273 | 8,155 | 26,365 | 36,911 | 184,555 | 1,228,609 | 6,143,045 | 8,600,263 | 43,001,315 |
| -1 | -5 | -7 | -35 | -233 | -1,165 | -1,631 | -5,273 | -8,155 | -26,365 | -36,911 | -184,555 | -1,228,609 | -6,143,045 | -8,600,263 | -43,001,315 |
