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 64,144,375, 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 | 64,144,375 | |
| -1 | -64,144,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,144,375.
Example:
1 x 64,144,375 = 64,144,375
and
-1 x -64,144,375 = 64,144,375
Notice both answers equal 64,144,375
With that explanation out of the way, let's continue. Next, we take the number 64,144,375 and divide it by 2:
64,144,375 ÷ 2 = 32,072,187.5
If the quotient is a whole number, then 2 and 32,072,187.5 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 | 64,144,375 | |
| -1 | -64,144,375 |
Now, we try dividing 64,144,375 by 3:
64,144,375 ÷ 3 = 21,381,458.3333
If the quotient is a whole number, then 3 and 21,381,458.3333 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 | 64,144,375 | |
| -1 | -64,144,375 |
Let's try dividing by 4:
64,144,375 ÷ 4 = 16,036,093.75
If the quotient is a whole number, then 4 and 16,036,093.75 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 | 64,144,375 | |
| -1 | 64,144,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 625 | 725 | 3,539 | 3,625 | 17,695 | 18,125 | 88,475 | 102,631 | 442,375 | 513,155 | 2,211,875 | 2,565,775 | 12,828,875 | 64,144,375 |
| -1 | -5 | -25 | -29 | -125 | -145 | -625 | -725 | -3,539 | -3,625 | -17,695 | -18,125 | -88,475 | -102,631 | -442,375 | -513,155 | -2,211,875 | -2,565,775 | -12,828,875 | -64,144,375 |
