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 124,341,119, 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 | 124,341,119 | |
| -1 | -124,341,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,341,119.
Example:
1 x 124,341,119 = 124,341,119
and
-1 x -124,341,119 = 124,341,119
Notice both answers equal 124,341,119
With that explanation out of the way, let's continue. Next, we take the number 124,341,119 and divide it by 2:
124,341,119 ÷ 2 = 62,170,559.5
If the quotient is a whole number, then 2 and 62,170,559.5 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 | 124,341,119 | |
| -1 | -124,341,119 |
Now, we try dividing 124,341,119 by 3:
124,341,119 ÷ 3 = 41,447,039.6667
If the quotient is a whole number, then 3 and 41,447,039.6667 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 | 124,341,119 | |
| -1 | -124,341,119 |
Let's try dividing by 4:
124,341,119 ÷ 4 = 31,085,279.75
If the quotient is a whole number, then 4 and 31,085,279.75 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 | 124,341,119 | |
| -1 | 124,341,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 73 | 427 | 511 | 3,989 | 4,453 | 27,923 | 31,171 | 243,329 | 291,197 | 1,703,303 | 2,038,379 | 17,763,017 | 124,341,119 |
| -1 | -7 | -61 | -73 | -427 | -511 | -3,989 | -4,453 | -27,923 | -31,171 | -243,329 | -291,197 | -1,703,303 | -2,038,379 | -17,763,017 | -124,341,119 |
