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 124,400,075, 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 | 124,400,075 | |
| -1 | -124,400,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,400,075.
Example:
1 x 124,400,075 = 124,400,075
and
-1 x -124,400,075 = 124,400,075
Notice both answers equal 124,400,075
With that explanation out of the way, let's continue. Next, we take the number 124,400,075 and divide it by 2:
124,400,075 ÷ 2 = 62,200,037.5
If the quotient is a whole number, then 2 and 62,200,037.5 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 | 124,400,075 | |
| -1 | -124,400,075 |
Now, we try dividing 124,400,075 by 3:
124,400,075 ÷ 3 = 41,466,691.6667
If the quotient is a whole number, then 3 and 41,466,691.6667 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 | 124,400,075 | |
| -1 | -124,400,075 |
Let's try dividing by 4:
124,400,075 ÷ 4 = 31,100,018.75
If the quotient is a whole number, then 4 and 31,100,018.75 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 | 124,400,075 | |
| -1 | 124,400,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 97 | 215 | 485 | 1,075 | 1,193 | 2,425 | 4,171 | 5,965 | 20,855 | 29,825 | 51,299 | 104,275 | 115,721 | 256,495 | 578,605 | 1,282,475 | 2,893,025 | 4,976,003 | 24,880,015 | 124,400,075 |
| -1 | -5 | -25 | -43 | -97 | -215 | -485 | -1,075 | -1,193 | -2,425 | -4,171 | -5,965 | -20,855 | -29,825 | -51,299 | -104,275 | -115,721 | -256,495 | -578,605 | -1,282,475 | -2,893,025 | -4,976,003 | -24,880,015 | -124,400,075 |
