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 524,254,415, 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 | 524,254,415 | |
| -1 | -524,254,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 524,254,415.
Example:
1 x 524,254,415 = 524,254,415
and
-1 x -524,254,415 = 524,254,415
Notice both answers equal 524,254,415
With that explanation out of the way, let's continue. Next, we take the number 524,254,415 and divide it by 2:
524,254,415 ÷ 2 = 262,127,207.5
If the quotient is a whole number, then 2 and 262,127,207.5 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 | 524,254,415 | |
| -1 | -524,254,415 |
Now, we try dividing 524,254,415 by 3:
524,254,415 ÷ 3 = 174,751,471.6667
If the quotient is a whole number, then 3 and 174,751,471.6667 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 | 524,254,415 | |
| -1 | -524,254,415 |
Let's try dividing by 4:
524,254,415 ÷ 4 = 131,063,603.75
If the quotient is a whole number, then 4 and 131,063,603.75 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 | 524,254,415 | |
| -1 | 524,254,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 355 | 1,207 | 6,035 | 86,869 | 434,345 | 1,476,773 | 6,167,699 | 7,383,865 | 30,838,495 | 104,850,883 | 524,254,415 |
| -1 | -5 | -17 | -71 | -85 | -355 | -1,207 | -6,035 | -86,869 | -434,345 | -1,476,773 | -6,167,699 | -7,383,865 | -30,838,495 | -104,850,883 | -524,254,415 |
