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 124,316,225, 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 | 124,316,225 | |
| -1 | -124,316,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,316,225.
Example:
1 x 124,316,225 = 124,316,225
and
-1 x -124,316,225 = 124,316,225
Notice both answers equal 124,316,225
With that explanation out of the way, let's continue. Next, we take the number 124,316,225 and divide it by 2:
124,316,225 ÷ 2 = 62,158,112.5
If the quotient is a whole number, then 2 and 62,158,112.5 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 | 124,316,225 | |
| -1 | -124,316,225 |
Now, we try dividing 124,316,225 by 3:
124,316,225 ÷ 3 = 41,438,741.6667
If the quotient is a whole number, then 3 and 41,438,741.6667 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 | 124,316,225 | |
| -1 | -124,316,225 |
Let's try dividing by 4:
124,316,225 ÷ 4 = 31,079,056.25
If the quotient is a whole number, then 4 and 31,079,056.25 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 | 124,316,225 | |
| -1 | 124,316,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 55 | 215 | 275 | 473 | 1,075 | 2,365 | 10,513 | 11,825 | 52,565 | 115,643 | 262,825 | 452,059 | 578,215 | 2,260,295 | 2,891,075 | 4,972,649 | 11,301,475 | 24,863,245 | 124,316,225 |
| -1 | -5 | -11 | -25 | -43 | -55 | -215 | -275 | -473 | -1,075 | -2,365 | -10,513 | -11,825 | -52,565 | -115,643 | -262,825 | -452,059 | -578,215 | -2,260,295 | -2,891,075 | -4,972,649 | -11,301,475 | -24,863,245 | -124,316,225 |
