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 64,113,445, 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 | 64,113,445 | |
| -1 | -64,113,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,113,445.
Example:
1 x 64,113,445 = 64,113,445
and
-1 x -64,113,445 = 64,113,445
Notice both answers equal 64,113,445
With that explanation out of the way, let's continue. Next, we take the number 64,113,445 and divide it by 2:
64,113,445 ÷ 2 = 32,056,722.5
If the quotient is a whole number, then 2 and 32,056,722.5 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 | 64,113,445 | |
| -1 | -64,113,445 |
Now, we try dividing 64,113,445 by 3:
64,113,445 ÷ 3 = 21,371,148.3333
If the quotient is a whole number, then 3 and 21,371,148.3333 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 | 64,113,445 | |
| -1 | -64,113,445 |
Let's try dividing by 4:
64,113,445 ÷ 4 = 16,028,361.25
If the quotient is a whole number, then 4 and 16,028,361.25 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 | 64,113,445 | |
| -1 | 64,113,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 233 | 1,165 | 2,563 | 5,003 | 12,815 | 25,015 | 55,033 | 275,165 | 1,165,699 | 5,828,495 | 12,822,689 | 64,113,445 |
| -1 | -5 | -11 | -55 | -233 | -1,165 | -2,563 | -5,003 | -12,815 | -25,015 | -55,033 | -275,165 | -1,165,699 | -5,828,495 | -12,822,689 | -64,113,445 |
