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 124,261,735, 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 | 124,261,735 | |
| -1 | -124,261,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,261,735.
Example:
1 x 124,261,735 = 124,261,735
and
-1 x -124,261,735 = 124,261,735
Notice both answers equal 124,261,735
With that explanation out of the way, let's continue. Next, we take the number 124,261,735 and divide it by 2:
124,261,735 ÷ 2 = 62,130,867.5
If the quotient is a whole number, then 2 and 62,130,867.5 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 | 124,261,735 | |
| -1 | -124,261,735 |
Now, we try dividing 124,261,735 by 3:
124,261,735 ÷ 3 = 41,420,578.3333
If the quotient is a whole number, then 3 and 41,420,578.3333 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 | 124,261,735 | |
| -1 | -124,261,735 |
Let's try dividing by 4:
124,261,735 ÷ 4 = 31,065,433.75
If the quotient is a whole number, then 4 and 31,065,433.75 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 | 124,261,735 | |
| -1 | 124,261,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 191 | 955 | 2,483 | 10,009 | 12,415 | 50,045 | 130,117 | 650,585 | 1,911,719 | 9,558,595 | 24,852,347 | 124,261,735 |
| -1 | -5 | -13 | -65 | -191 | -955 | -2,483 | -10,009 | -12,415 | -50,045 | -130,117 | -650,585 | -1,911,719 | -9,558,595 | -24,852,347 | -124,261,735 |
