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 53,515,345, 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 | 53,515,345 | |
| -1 | -53,515,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,515,345.
Example:
1 x 53,515,345 = 53,515,345
and
-1 x -53,515,345 = 53,515,345
Notice both answers equal 53,515,345
With that explanation out of the way, let's continue. Next, we take the number 53,515,345 and divide it by 2:
53,515,345 ÷ 2 = 26,757,672.5
If the quotient is a whole number, then 2 and 26,757,672.5 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 | 53,515,345 | |
| -1 | -53,515,345 |
Now, we try dividing 53,515,345 by 3:
53,515,345 ÷ 3 = 17,838,448.3333
If the quotient is a whole number, then 3 and 17,838,448.3333 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 | 53,515,345 | |
| -1 | -53,515,345 |
Let's try dividing by 4:
53,515,345 ÷ 4 = 13,378,836.25
If the quotient is a whole number, then 4 and 13,378,836.25 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 | 53,515,345 | |
| -1 | 53,515,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 163 | 815 | 2,119 | 5,051 | 10,595 | 25,255 | 65,663 | 328,315 | 823,313 | 4,116,565 | 10,703,069 | 53,515,345 |
| -1 | -5 | -13 | -65 | -163 | -815 | -2,119 | -5,051 | -10,595 | -25,255 | -65,663 | -328,315 | -823,313 | -4,116,565 | -10,703,069 | -53,515,345 |
