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 525,435,415, 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 | 525,435,415 | |
| -1 | -525,435,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 525,435,415.
Example:
1 x 525,435,415 = 525,435,415
and
-1 x -525,435,415 = 525,435,415
Notice both answers equal 525,435,415
With that explanation out of the way, let's continue. Next, we take the number 525,435,415 and divide it by 2:
525,435,415 ÷ 2 = 262,717,707.5
If the quotient is a whole number, then 2 and 262,717,707.5 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 | 525,435,415 | |
| -1 | -525,435,415 |
Now, we try dividing 525,435,415 by 3:
525,435,415 ÷ 3 = 175,145,138.3333
If the quotient is a whole number, then 3 and 175,145,138.3333 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 | 525,435,415 | |
| -1 | -525,435,415 |
Let's try dividing by 4:
525,435,415 ÷ 4 = 131,358,853.75
If the quotient is a whole number, then 4 and 131,358,853.75 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 | 525,435,415 | |
| -1 | 525,435,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 137 | 295 | 685 | 8,083 | 13,001 | 40,415 | 65,005 | 767,059 | 1,781,137 | 3,835,295 | 8,905,685 | 105,087,083 | 525,435,415 |
| -1 | -5 | -59 | -137 | -295 | -685 | -8,083 | -13,001 | -40,415 | -65,005 | -767,059 | -1,781,137 | -3,835,295 | -8,905,685 | -105,087,083 | -525,435,415 |
