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 43,689,125, 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 | 43,689,125 | |
| -1 | -43,689,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,689,125.
Example:
1 x 43,689,125 = 43,689,125
and
-1 x -43,689,125 = 43,689,125
Notice both answers equal 43,689,125
With that explanation out of the way, let's continue. Next, we take the number 43,689,125 and divide it by 2:
43,689,125 ÷ 2 = 21,844,562.5
If the quotient is a whole number, then 2 and 21,844,562.5 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 | 43,689,125 | |
| -1 | -43,689,125 |
Now, we try dividing 43,689,125 by 3:
43,689,125 ÷ 3 = 14,563,041.6667
If the quotient is a whole number, then 3 and 14,563,041.6667 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 | 43,689,125 | |
| -1 | -43,689,125 |
Let's try dividing by 4:
43,689,125 ÷ 4 = 10,922,281.25
If the quotient is a whole number, then 4 and 10,922,281.25 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 | 43,689,125 | |
| -1 | 43,689,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 125 | 415 | 2,075 | 4,211 | 10,375 | 21,055 | 105,275 | 349,513 | 526,375 | 1,747,565 | 8,737,825 | 43,689,125 |
| -1 | -5 | -25 | -83 | -125 | -415 | -2,075 | -4,211 | -10,375 | -21,055 | -105,275 | -349,513 | -526,375 | -1,747,565 | -8,737,825 | -43,689,125 |
