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 125,417,347, 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 | 125,417,347 | |
| -1 | -125,417,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,417,347.
Example:
1 x 125,417,347 = 125,417,347
and
-1 x -125,417,347 = 125,417,347
Notice both answers equal 125,417,347
With that explanation out of the way, let's continue. Next, we take the number 125,417,347 and divide it by 2:
125,417,347 ÷ 2 = 62,708,673.5
If the quotient is a whole number, then 2 and 62,708,673.5 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 | 125,417,347 | |
| -1 | -125,417,347 |
Now, we try dividing 125,417,347 by 3:
125,417,347 ÷ 3 = 41,805,782.3333
If the quotient is a whole number, then 3 and 41,805,782.3333 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 | 125,417,347 | |
| -1 | -125,417,347 |
Let's try dividing by 4:
125,417,347 ÷ 4 = 31,354,336.75
If the quotient is a whole number, then 4 and 31,354,336.75 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 | 125,417,347 | |
| -1 | 125,417,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 121 | 187 | 209 | 323 | 2,057 | 2,299 | 3,209 | 3,553 | 35,299 | 39,083 | 54,553 | 60,971 | 388,289 | 600,083 | 670,681 | 1,036,507 | 6,600,913 | 7,377,491 | 11,401,577 | 125,417,347 |
| -1 | -11 | -17 | -19 | -121 | -187 | -209 | -323 | -2,057 | -2,299 | -3,209 | -3,553 | -35,299 | -39,083 | -54,553 | -60,971 | -388,289 | -600,083 | -670,681 | -1,036,507 | -6,600,913 | -7,377,491 | -11,401,577 | -125,417,347 |
