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 53,366,509, 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 | 53,366,509 | |
| -1 | -53,366,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,366,509.
Example:
1 x 53,366,509 = 53,366,509
and
-1 x -53,366,509 = 53,366,509
Notice both answers equal 53,366,509
With that explanation out of the way, let's continue. Next, we take the number 53,366,509 and divide it by 2:
53,366,509 ÷ 2 = 26,683,254.5
If the quotient is a whole number, then 2 and 26,683,254.5 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 | 53,366,509 | |
| -1 | -53,366,509 |
Now, we try dividing 53,366,509 by 3:
53,366,509 ÷ 3 = 17,788,836.3333
If the quotient is a whole number, then 3 and 17,788,836.3333 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 | 53,366,509 | |
| -1 | -53,366,509 |
Let's try dividing by 4:
53,366,509 ÷ 4 = 13,341,627.25
If the quotient is a whole number, then 4 and 13,341,627.25 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 | 53,366,509 | |
| -1 | 53,366,509 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 109 | 161 | 763 | 2,507 | 3,041 | 17,549 | 21,287 | 69,943 | 331,469 | 489,601 | 2,320,283 | 7,623,787 | 53,366,509 |
| -1 | -7 | -23 | -109 | -161 | -763 | -2,507 | -3,041 | -17,549 | -21,287 | -69,943 | -331,469 | -489,601 | -2,320,283 | -7,623,787 | -53,366,509 |
