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 43,612,315, 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 | 43,612,315 | |
| -1 | -43,612,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,612,315.
Example:
1 x 43,612,315 = 43,612,315
and
-1 x -43,612,315 = 43,612,315
Notice both answers equal 43,612,315
With that explanation out of the way, let's continue. Next, we take the number 43,612,315 and divide it by 2:
43,612,315 ÷ 2 = 21,806,157.5
If the quotient is a whole number, then 2 and 21,806,157.5 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 | 43,612,315 | |
| -1 | -43,612,315 |
Now, we try dividing 43,612,315 by 3:
43,612,315 ÷ 3 = 14,537,438.3333
If the quotient is a whole number, then 3 and 14,537,438.3333 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 | 43,612,315 | |
| -1 | -43,612,315 |
Let's try dividing by 4:
43,612,315 ÷ 4 = 10,903,078.75
If the quotient is a whole number, then 4 and 10,903,078.75 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 | 43,612,315 | |
| -1 | 43,612,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 3,895 | 11,197 | 55,985 | 212,743 | 459,077 | 1,063,715 | 2,295,385 | 8,722,463 | 43,612,315 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -3,895 | -11,197 | -55,985 | -212,743 | -459,077 | -1,063,715 | -2,295,385 | -8,722,463 | -43,612,315 |
