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 525,454,345, 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 | 525,454,345 | |
| -1 | -525,454,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,454,345.
Example:
1 x 525,454,345 = 525,454,345
and
-1 x -525,454,345 = 525,454,345
Notice both answers equal 525,454,345
With that explanation out of the way, let's continue. Next, we take the number 525,454,345 and divide it by 2:
525,454,345 ÷ 2 = 262,727,172.5
If the quotient is a whole number, then 2 and 262,727,172.5 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 | 525,454,345 | |
| -1 | -525,454,345 |
Now, we try dividing 525,454,345 by 3:
525,454,345 ÷ 3 = 175,151,448.3333
If the quotient is a whole number, then 3 and 175,151,448.3333 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 | 525,454,345 | |
| -1 | -525,454,345 |
Let's try dividing by 4:
525,454,345 ÷ 4 = 131,363,586.25
If the quotient is a whole number, then 4 and 131,363,586.25 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 | 525,454,345 | |
| -1 | 525,454,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 2,617 | 3,089 | 13,085 | 15,445 | 34,021 | 40,157 | 170,105 | 200,785 | 8,083,913 | 40,419,565 | 105,090,869 | 525,454,345 |
| -1 | -5 | -13 | -65 | -2,617 | -3,089 | -13,085 | -15,445 | -34,021 | -40,157 | -170,105 | -200,785 | -8,083,913 | -40,419,565 | -105,090,869 | -525,454,345 |
