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 125,422,843, 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 | 125,422,843 | |
| -1 | -125,422,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,422,843.
Example:
1 x 125,422,843 = 125,422,843
and
-1 x -125,422,843 = 125,422,843
Notice both answers equal 125,422,843
With that explanation out of the way, let's continue. Next, we take the number 125,422,843 and divide it by 2:
125,422,843 ÷ 2 = 62,711,421.5
If the quotient is a whole number, then 2 and 62,711,421.5 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 | 125,422,843 | |
| -1 | -125,422,843 |
Now, we try dividing 125,422,843 by 3:
125,422,843 ÷ 3 = 41,807,614.3333
If the quotient is a whole number, then 3 and 41,807,614.3333 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 | 125,422,843 | |
| -1 | -125,422,843 |
Let's try dividing by 4:
125,422,843 ÷ 4 = 31,355,710.75
If the quotient is a whole number, then 4 and 31,355,710.75 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 | 125,422,843 | |
| -1 | 125,422,843 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 97 | 169 | 679 | 1,093 | 1,183 | 1,261 | 7,651 | 8,827 | 14,209 | 16,393 | 99,463 | 106,021 | 114,751 | 184,717 | 742,147 | 1,293,019 | 1,378,273 | 9,647,911 | 17,917,549 | 125,422,843 |
| -1 | -7 | -13 | -91 | -97 | -169 | -679 | -1,093 | -1,183 | -1,261 | -7,651 | -8,827 | -14,209 | -16,393 | -99,463 | -106,021 | -114,751 | -184,717 | -742,147 | -1,293,019 | -1,378,273 | -9,647,911 | -17,917,549 | -125,422,843 |
