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 124,102,675, 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 | 124,102,675 | |
| -1 | -124,102,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,102,675.
Example:
1 x 124,102,675 = 124,102,675
and
-1 x -124,102,675 = 124,102,675
Notice both answers equal 124,102,675
With that explanation out of the way, let's continue. Next, we take the number 124,102,675 and divide it by 2:
124,102,675 ÷ 2 = 62,051,337.5
If the quotient is a whole number, then 2 and 62,051,337.5 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 | 124,102,675 | |
| -1 | -124,102,675 |
Now, we try dividing 124,102,675 by 3:
124,102,675 ÷ 3 = 41,367,558.3333
If the quotient is a whole number, then 3 and 41,367,558.3333 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 | 124,102,675 | |
| -1 | -124,102,675 |
Let's try dividing by 4:
124,102,675 ÷ 4 = 31,025,668.75
If the quotient is a whole number, then 4 and 31,025,668.75 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 | 124,102,675 | |
| -1 | 124,102,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 139 | 355 | 503 | 695 | 1,775 | 2,515 | 3,475 | 9,869 | 12,575 | 35,713 | 49,345 | 69,917 | 178,565 | 246,725 | 349,585 | 892,825 | 1,747,925 | 4,964,107 | 24,820,535 | 124,102,675 |
| -1 | -5 | -25 | -71 | -139 | -355 | -503 | -695 | -1,775 | -2,515 | -3,475 | -9,869 | -12,575 | -35,713 | -49,345 | -69,917 | -178,565 | -246,725 | -349,585 | -892,825 | -1,747,925 | -4,964,107 | -24,820,535 | -124,102,675 |
