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 124,154,437, 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 | 124,154,437 | |
| -1 | -124,154,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,154,437.
Example:
1 x 124,154,437 = 124,154,437
and
-1 x -124,154,437 = 124,154,437
Notice both answers equal 124,154,437
With that explanation out of the way, let's continue. Next, we take the number 124,154,437 and divide it by 2:
124,154,437 ÷ 2 = 62,077,218.5
If the quotient is a whole number, then 2 and 62,077,218.5 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 | 124,154,437 | |
| -1 | -124,154,437 |
Now, we try dividing 124,154,437 by 3:
124,154,437 ÷ 3 = 41,384,812.3333
If the quotient is a whole number, then 3 and 41,384,812.3333 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 | 124,154,437 | |
| -1 | -124,154,437 |
Let's try dividing by 4:
124,154,437 ÷ 4 = 31,038,609.25
If the quotient is a whole number, then 4 and 31,038,609.25 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 | 124,154,437 | |
| -1 | 124,154,437 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 41 | 253 | 451 | 943 | 10,373 | 11,969 | 131,659 | 275,287 | 490,729 | 3,028,157 | 5,398,019 | 11,286,767 | 124,154,437 |
| -1 | -11 | -23 | -41 | -253 | -451 | -943 | -10,373 | -11,969 | -131,659 | -275,287 | -490,729 | -3,028,157 | -5,398,019 | -11,286,767 | -124,154,437 |
