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 122,360,525, 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 | 122,360,525 | |
| -1 | -122,360,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,360,525.
Example:
1 x 122,360,525 = 122,360,525
and
-1 x -122,360,525 = 122,360,525
Notice both answers equal 122,360,525
With that explanation out of the way, let's continue. Next, we take the number 122,360,525 and divide it by 2:
122,360,525 ÷ 2 = 61,180,262.5
If the quotient is a whole number, then 2 and 61,180,262.5 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 | 122,360,525 | |
| -1 | -122,360,525 |
Now, we try dividing 122,360,525 by 3:
122,360,525 ÷ 3 = 40,786,841.6667
If the quotient is a whole number, then 3 and 40,786,841.6667 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 | 122,360,525 | |
| -1 | -122,360,525 |
Let's try dividing by 4:
122,360,525 ÷ 4 = 30,590,131.25
If the quotient is a whole number, then 4 and 30,590,131.25 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 | 122,360,525 | |
| -1 | 122,360,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 181 | 905 | 1,267 | 3,863 | 4,525 | 6,335 | 19,315 | 27,041 | 31,675 | 96,575 | 135,205 | 676,025 | 699,203 | 3,496,015 | 4,894,421 | 17,480,075 | 24,472,105 | 122,360,525 |
| -1 | -5 | -7 | -25 | -35 | -175 | -181 | -905 | -1,267 | -3,863 | -4,525 | -6,335 | -19,315 | -27,041 | -31,675 | -96,575 | -135,205 | -676,025 | -699,203 | -3,496,015 | -4,894,421 | -17,480,075 | -24,472,105 | -122,360,525 |
