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 124,362,173, 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 | 124,362,173 | |
| -1 | -124,362,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,362,173.
Example:
1 x 124,362,173 = 124,362,173
and
-1 x -124,362,173 = 124,362,173
Notice both answers equal 124,362,173
With that explanation out of the way, let's continue. Next, we take the number 124,362,173 and divide it by 2:
124,362,173 ÷ 2 = 62,181,086.5
If the quotient is a whole number, then 2 and 62,181,086.5 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 | 124,362,173 | |
| -1 | -124,362,173 |
Now, we try dividing 124,362,173 by 3:
124,362,173 ÷ 3 = 41,454,057.6667
If the quotient is a whole number, then 3 and 41,454,057.6667 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 | 124,362,173 | |
| -1 | -124,362,173 |
Let's try dividing by 4:
124,362,173 ÷ 4 = 31,090,543.25
If the quotient is a whole number, then 4 and 31,090,543.25 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 | 124,362,173 | |
| -1 | 124,362,173 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 31 | 299 | 403 | 713 | 9,269 | 13,417 | 174,421 | 308,591 | 415,927 | 4,011,683 | 5,407,051 | 9,566,321 | 124,362,173 |
| -1 | -13 | -23 | -31 | -299 | -403 | -713 | -9,269 | -13,417 | -174,421 | -308,591 | -415,927 | -4,011,683 | -5,407,051 | -9,566,321 | -124,362,173 |
