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 43,525,447, 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 | 43,525,447 | |
| -1 | -43,525,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,525,447.
Example:
1 x 43,525,447 = 43,525,447
and
-1 x -43,525,447 = 43,525,447
Notice both answers equal 43,525,447
With that explanation out of the way, let's continue. Next, we take the number 43,525,447 and divide it by 2:
43,525,447 ÷ 2 = 21,762,723.5
If the quotient is a whole number, then 2 and 21,762,723.5 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 | 43,525,447 | |
| -1 | -43,525,447 |
Now, we try dividing 43,525,447 by 3:
43,525,447 ÷ 3 = 14,508,482.3333
If the quotient is a whole number, then 3 and 14,508,482.3333 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 | 43,525,447 | |
| -1 | -43,525,447 |
Let's try dividing by 4:
43,525,447 ÷ 4 = 10,881,361.75
If the quotient is a whole number, then 4 and 10,881,361.75 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 | 43,525,447 | |
| -1 | 43,525,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 73 | 133 | 511 | 1,387 | 4,483 | 9,709 | 31,381 | 85,177 | 327,259 | 596,239 | 2,290,813 | 6,217,921 | 43,525,447 |
| -1 | -7 | -19 | -73 | -133 | -511 | -1,387 | -4,483 | -9,709 | -31,381 | -85,177 | -327,259 | -596,239 | -2,290,813 | -6,217,921 | -43,525,447 |
