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 64,693,573, 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 | 64,693,573 | |
| -1 | -64,693,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,693,573.
Example:
1 x 64,693,573 = 64,693,573
and
-1 x -64,693,573 = 64,693,573
Notice both answers equal 64,693,573
With that explanation out of the way, let's continue. Next, we take the number 64,693,573 and divide it by 2:
64,693,573 ÷ 2 = 32,346,786.5
If the quotient is a whole number, then 2 and 32,346,786.5 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 | 64,693,573 | |
| -1 | -64,693,573 |
Now, we try dividing 64,693,573 by 3:
64,693,573 ÷ 3 = 21,564,524.3333
If the quotient is a whole number, then 3 and 21,564,524.3333 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 | 64,693,573 | |
| -1 | -64,693,573 |
Let's try dividing by 4:
64,693,573 ÷ 4 = 16,173,393.25
If the quotient is a whole number, then 4 and 16,173,393.25 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 | 64,693,573 | |
| -1 | 64,693,573 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 49 | 329 | 343 | 2,303 | 4,013 | 16,121 | 28,091 | 188,611 | 196,637 | 1,320,277 | 1,376,459 | 9,241,939 | 64,693,573 |
| -1 | -7 | -47 | -49 | -329 | -343 | -2,303 | -4,013 | -16,121 | -28,091 | -188,611 | -196,637 | -1,320,277 | -1,376,459 | -9,241,939 | -64,693,573 |
