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 64,454,137, 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 | 64,454,137 | |
| -1 | -64,454,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,454,137.
Example:
1 x 64,454,137 = 64,454,137
and
-1 x -64,454,137 = 64,454,137
Notice both answers equal 64,454,137
With that explanation out of the way, let's continue. Next, we take the number 64,454,137 and divide it by 2:
64,454,137 ÷ 2 = 32,227,068.5
If the quotient is a whole number, then 2 and 32,227,068.5 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 | 64,454,137 | |
| -1 | -64,454,137 |
Now, we try dividing 64,454,137 by 3:
64,454,137 ÷ 3 = 21,484,712.3333
If the quotient is a whole number, then 3 and 21,484,712.3333 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 | 64,454,137 | |
| -1 | -64,454,137 |
Let's try dividing by 4:
64,454,137 ÷ 4 = 16,113,534.25
If the quotient is a whole number, then 4 and 16,113,534.25 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 | 64,454,137 | |
| -1 | 64,454,137 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 59 | 209 | 649 | 1,121 | 5,227 | 12,331 | 57,497 | 99,313 | 308,393 | 1,092,443 | 3,392,323 | 5,859,467 | 64,454,137 |
| -1 | -11 | -19 | -59 | -209 | -649 | -1,121 | -5,227 | -12,331 | -57,497 | -99,313 | -308,393 | -1,092,443 | -3,392,323 | -5,859,467 | -64,454,137 |
