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 124,514,159, 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 | 124,514,159 | |
| -1 | -124,514,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,514,159.
Example:
1 x 124,514,159 = 124,514,159
and
-1 x -124,514,159 = 124,514,159
Notice both answers equal 124,514,159
With that explanation out of the way, let's continue. Next, we take the number 124,514,159 and divide it by 2:
124,514,159 ÷ 2 = 62,257,079.5
If the quotient is a whole number, then 2 and 62,257,079.5 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 | 124,514,159 | |
| -1 | -124,514,159 |
Now, we try dividing 124,514,159 by 3:
124,514,159 ÷ 3 = 41,504,719.6667
If the quotient is a whole number, then 3 and 41,504,719.6667 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 | 124,514,159 | |
| -1 | -124,514,159 |
Let's try dividing by 4:
124,514,159 ÷ 4 = 31,128,539.75
If the quotient is a whole number, then 4 and 31,128,539.75 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 | 124,514,159 | |
| -1 | 124,514,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 293 | 2,051 | 3,223 | 5,519 | 22,561 | 38,633 | 60,709 | 424,963 | 1,617,067 | 11,319,469 | 17,787,737 | 124,514,159 |
| -1 | -7 | -11 | -77 | -293 | -2,051 | -3,223 | -5,519 | -22,561 | -38,633 | -60,709 | -424,963 | -1,617,067 | -11,319,469 | -17,787,737 | -124,514,159 |
