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 253,600,429, 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 | 253,600,429 | |
| -1 | -253,600,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,600,429.
Example:
1 x 253,600,429 = 253,600,429
and
-1 x -253,600,429 = 253,600,429
Notice both answers equal 253,600,429
With that explanation out of the way, let's continue. Next, we take the number 253,600,429 and divide it by 2:
253,600,429 ÷ 2 = 126,800,214.5
If the quotient is a whole number, then 2 and 126,800,214.5 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 | 253,600,429 | |
| -1 | -253,600,429 |
Now, we try dividing 253,600,429 by 3:
253,600,429 ÷ 3 = 84,533,476.3333
If the quotient is a whole number, then 3 and 84,533,476.3333 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 | 253,600,429 | |
| -1 | -253,600,429 |
Let's try dividing by 4:
253,600,429 ÷ 4 = 63,400,107.25
If the quotient is a whole number, then 4 and 63,400,107.25 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 | 253,600,429 | |
| -1 | 253,600,429 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 557 | 589 | 773 | 10,583 | 14,687 | 17,267 | 23,963 | 328,073 | 430,561 | 455,297 | 8,180,659 | 13,347,391 | 253,600,429 |
| -1 | -19 | -31 | -557 | -589 | -773 | -10,583 | -14,687 | -17,267 | -23,963 | -328,073 | -430,561 | -455,297 | -8,180,659 | -13,347,391 | -253,600,429 |
