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 65,343,575, 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 | 65,343,575 | |
| -1 | -65,343,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,343,575.
Example:
1 x 65,343,575 = 65,343,575
and
-1 x -65,343,575 = 65,343,575
Notice both answers equal 65,343,575
With that explanation out of the way, let's continue. Next, we take the number 65,343,575 and divide it by 2:
65,343,575 ÷ 2 = 32,671,787.5
If the quotient is a whole number, then 2 and 32,671,787.5 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 | 65,343,575 | |
| -1 | -65,343,575 |
Now, we try dividing 65,343,575 by 3:
65,343,575 ÷ 3 = 21,781,191.6667
If the quotient is a whole number, then 3 and 21,781,191.6667 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 | 65,343,575 | |
| -1 | -65,343,575 |
Let's try dividing by 4:
65,343,575 ÷ 4 = 16,335,893.75
If the quotient is a whole number, then 4 and 16,335,893.75 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 | 65,343,575 | |
| -1 | 65,343,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 6,325 | 10,331 | 51,655 | 113,641 | 237,613 | 258,275 | 568,205 | 1,188,065 | 2,613,743 | 2,841,025 | 5,940,325 | 13,068,715 | 65,343,575 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -6,325 | -10,331 | -51,655 | -113,641 | -237,613 | -258,275 | -568,205 | -1,188,065 | -2,613,743 | -2,841,025 | -5,940,325 | -13,068,715 | -65,343,575 |
