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 61,514,365, 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 | 61,514,365 | |
| -1 | -61,514,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,514,365.
Example:
1 x 61,514,365 = 61,514,365
and
-1 x -61,514,365 = 61,514,365
Notice both answers equal 61,514,365
With that explanation out of the way, let's continue. Next, we take the number 61,514,365 and divide it by 2:
61,514,365 ÷ 2 = 30,757,182.5
If the quotient is a whole number, then 2 and 30,757,182.5 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 | 61,514,365 | |
| -1 | -61,514,365 |
Now, we try dividing 61,514,365 by 3:
61,514,365 ÷ 3 = 20,504,788.3333
If the quotient is a whole number, then 3 and 20,504,788.3333 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 | 61,514,365 | |
| -1 | -61,514,365 |
Let's try dividing by 4:
61,514,365 ÷ 4 = 15,378,591.25
If the quotient is a whole number, then 4 and 15,378,591.25 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 | 61,514,365 | |
| -1 | 61,514,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 38,567 | 192,835 | 424,237 | 1,118,443 | 2,121,185 | 5,592,215 | 12,302,873 | 61,514,365 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -38,567 | -192,835 | -424,237 | -1,118,443 | -2,121,185 | -5,592,215 | -12,302,873 | -61,514,365 |
