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 193,525,145, 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 | 193,525,145 | |
| -1 | -193,525,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 193,525,145.
Example:
1 x 193,525,145 = 193,525,145
and
-1 x -193,525,145 = 193,525,145
Notice both answers equal 193,525,145
With that explanation out of the way, let's continue. Next, we take the number 193,525,145 and divide it by 2:
193,525,145 ÷ 2 = 96,762,572.5
If the quotient is a whole number, then 2 and 96,762,572.5 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 | 193,525,145 | |
| -1 | -193,525,145 |
Now, we try dividing 193,525,145 by 3:
193,525,145 ÷ 3 = 64,508,381.6667
If the quotient is a whole number, then 3 and 64,508,381.6667 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 | 193,525,145 | |
| -1 | -193,525,145 |
Let's try dividing by 4:
193,525,145 ÷ 4 = 48,381,286.25
If the quotient is a whole number, then 4 and 48,381,286.25 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 | 193,525,145 | |
| -1 | 193,525,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 52,517 | 262,585 | 577,687 | 2,888,435 | 3,518,639 | 17,593,195 | 38,705,029 | 193,525,145 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -52,517 | -262,585 | -577,687 | -2,888,435 | -3,518,639 | -17,593,195 | -38,705,029 | -193,525,145 |
