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 43,650,139, 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 | 43,650,139 | |
| -1 | -43,650,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,650,139.
Example:
1 x 43,650,139 = 43,650,139
and
-1 x -43,650,139 = 43,650,139
Notice both answers equal 43,650,139
With that explanation out of the way, let's continue. Next, we take the number 43,650,139 and divide it by 2:
43,650,139 ÷ 2 = 21,825,069.5
If the quotient is a whole number, then 2 and 21,825,069.5 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 | 43,650,139 | |
| -1 | -43,650,139 |
Now, we try dividing 43,650,139 by 3:
43,650,139 ÷ 3 = 14,550,046.3333
If the quotient is a whole number, then 3 and 14,550,046.3333 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 | 43,650,139 | |
| -1 | -43,650,139 |
Let's try dividing by 4:
43,650,139 ÷ 4 = 10,912,534.75
If the quotient is a whole number, then 4 and 10,912,534.75 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 | 43,650,139 | |
| -1 | 43,650,139 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 89 | 403 | 1,157 | 1,217 | 2,759 | 15,821 | 35,867 | 37,727 | 108,313 | 490,451 | 1,408,069 | 3,357,703 | 43,650,139 |
| -1 | -13 | -31 | -89 | -403 | -1,157 | -1,217 | -2,759 | -15,821 | -35,867 | -37,727 | -108,313 | -490,451 | -1,408,069 | -3,357,703 | -43,650,139 |
