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 42,944,389, 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 | 42,944,389 | |
| -1 | -42,944,389 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,944,389.
Example:
1 x 42,944,389 = 42,944,389
and
-1 x -42,944,389 = 42,944,389
Notice both answers equal 42,944,389
With that explanation out of the way, let's continue. Next, we take the number 42,944,389 and divide it by 2:
42,944,389 ÷ 2 = 21,472,194.5
If the quotient is a whole number, then 2 and 21,472,194.5 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 | 42,944,389 | |
| -1 | -42,944,389 |
Now, we try dividing 42,944,389 by 3:
42,944,389 ÷ 3 = 14,314,796.3333
If the quotient is a whole number, then 3 and 14,314,796.3333 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 | 42,944,389 | |
| -1 | -42,944,389 |
Let's try dividing by 4:
42,944,389 ÷ 4 = 10,736,097.25
If the quotient is a whole number, then 4 and 10,736,097.25 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 | 42,944,389 | |
| -1 | 42,944,389 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 59 | 551 | 1,121 | 1,321 | 1,711 | 25,099 | 32,509 | 38,309 | 77,939 | 727,871 | 1,480,841 | 2,260,231 | 42,944,389 |
| -1 | -19 | -29 | -59 | -551 | -1,121 | -1,321 | -1,711 | -25,099 | -32,509 | -38,309 | -77,939 | -727,871 | -1,480,841 | -2,260,231 | -42,944,389 |
