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 64,064,545, 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 | 64,064,545 | |
| -1 | -64,064,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,064,545.
Example:
1 x 64,064,545 = 64,064,545
and
-1 x -64,064,545 = 64,064,545
Notice both answers equal 64,064,545
With that explanation out of the way, let's continue. Next, we take the number 64,064,545 and divide it by 2:
64,064,545 ÷ 2 = 32,032,272.5
If the quotient is a whole number, then 2 and 32,032,272.5 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 | 64,064,545 | |
| -1 | -64,064,545 |
Now, we try dividing 64,064,545 by 3:
64,064,545 ÷ 3 = 21,354,848.3333
If the quotient is a whole number, then 3 and 21,354,848.3333 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 | 64,064,545 | |
| -1 | -64,064,545 |
Let's try dividing by 4:
64,064,545 ÷ 4 = 16,016,136.25
If the quotient is a whole number, then 4 and 16,016,136.25 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 | 64,064,545 | |
| -1 | 64,064,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 53 | 115 | 265 | 457 | 529 | 1,219 | 2,285 | 2,645 | 6,095 | 10,511 | 24,221 | 28,037 | 52,555 | 121,105 | 140,185 | 241,753 | 557,083 | 1,208,765 | 2,785,415 | 12,812,909 | 64,064,545 |
| -1 | -5 | -23 | -53 | -115 | -265 | -457 | -529 | -1,219 | -2,285 | -2,645 | -6,095 | -10,511 | -24,221 | -28,037 | -52,555 | -121,105 | -140,185 | -241,753 | -557,083 | -1,208,765 | -2,785,415 | -12,812,909 | -64,064,545 |
