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 65,504,545, 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 | 65,504,545 | |
| -1 | -65,504,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,504,545.
Example:
1 x 65,504,545 = 65,504,545
and
-1 x -65,504,545 = 65,504,545
Notice both answers equal 65,504,545
With that explanation out of the way, let's continue. Next, we take the number 65,504,545 and divide it by 2:
65,504,545 ÷ 2 = 32,752,272.5
If the quotient is a whole number, then 2 and 32,752,272.5 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 | 65,504,545 | |
| -1 | -65,504,545 |
Now, we try dividing 65,504,545 by 3:
65,504,545 ÷ 3 = 21,834,848.3333
If the quotient is a whole number, then 3 and 21,834,848.3333 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 | 65,504,545 | |
| -1 | -65,504,545 |
Let's try dividing by 4:
65,504,545 ÷ 4 = 16,376,136.25
If the quotient is a whole number, then 4 and 16,376,136.25 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 | 65,504,545 | |
| -1 | 65,504,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 293 | 305 | 733 | 1,465 | 3,665 | 17,873 | 44,713 | 89,365 | 214,769 | 223,565 | 1,073,845 | 13,100,909 | 65,504,545 |
| -1 | -5 | -61 | -293 | -305 | -733 | -1,465 | -3,665 | -17,873 | -44,713 | -89,365 | -214,769 | -223,565 | -1,073,845 | -13,100,909 | -65,504,545 |
