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 120,044,527, 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 | 120,044,527 | |
| -1 | -120,044,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,044,527.
Example:
1 x 120,044,527 = 120,044,527
and
-1 x -120,044,527 = 120,044,527
Notice both answers equal 120,044,527
With that explanation out of the way, let's continue. Next, we take the number 120,044,527 and divide it by 2:
120,044,527 ÷ 2 = 60,022,263.5
If the quotient is a whole number, then 2 and 60,022,263.5 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 | 120,044,527 | |
| -1 | -120,044,527 |
Now, we try dividing 120,044,527 by 3:
120,044,527 ÷ 3 = 40,014,842.3333
If the quotient is a whole number, then 3 and 40,014,842.3333 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 | 120,044,527 | |
| -1 | -120,044,527 |
Let's try dividing by 4:
120,044,527 ÷ 4 = 30,011,131.75
If the quotient is a whole number, then 4 and 30,011,131.75 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 | 120,044,527 | |
| -1 | 120,044,527 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 173 | 619 | 1,121 | 3,287 | 10,207 | 11,761 | 36,521 | 107,087 | 193,933 | 693,899 | 2,034,653 | 6,318,133 | 120,044,527 |
| -1 | -19 | -59 | -173 | -619 | -1,121 | -3,287 | -10,207 | -11,761 | -36,521 | -107,087 | -193,933 | -693,899 | -2,034,653 | -6,318,133 | -120,044,527 |
