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 64,822,415, 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 | 64,822,415 | |
| -1 | -64,822,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,822,415.
Example:
1 x 64,822,415 = 64,822,415
and
-1 x -64,822,415 = 64,822,415
Notice both answers equal 64,822,415
With that explanation out of the way, let's continue. Next, we take the number 64,822,415 and divide it by 2:
64,822,415 ÷ 2 = 32,411,207.5
If the quotient is a whole number, then 2 and 32,411,207.5 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 | 64,822,415 | |
| -1 | -64,822,415 |
Now, we try dividing 64,822,415 by 3:
64,822,415 ÷ 3 = 21,607,471.6667
If the quotient is a whole number, then 3 and 21,607,471.6667 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 | 64,822,415 | |
| -1 | -64,822,415 |
Let's try dividing by 4:
64,822,415 ÷ 4 = 16,205,603.75
If the quotient is a whole number, then 4 and 16,205,603.75 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 | 64,822,415 | |
| -1 | 64,822,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 31,391 | 156,955 | 219,737 | 1,098,685 | 1,852,069 | 9,260,345 | 12,964,483 | 64,822,415 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -31,391 | -156,955 | -219,737 | -1,098,685 | -1,852,069 | -9,260,345 | -12,964,483 | -64,822,415 |
