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 64,562,113, 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 | 64,562,113 | |
| -1 | -64,562,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,562,113.
Example:
1 x 64,562,113 = 64,562,113
and
-1 x -64,562,113 = 64,562,113
Notice both answers equal 64,562,113
With that explanation out of the way, let's continue. Next, we take the number 64,562,113 and divide it by 2:
64,562,113 ÷ 2 = 32,281,056.5
If the quotient is a whole number, then 2 and 32,281,056.5 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 | 64,562,113 | |
| -1 | -64,562,113 |
Now, we try dividing 64,562,113 by 3:
64,562,113 ÷ 3 = 21,520,704.3333
If the quotient is a whole number, then 3 and 21,520,704.3333 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 | 64,562,113 | |
| -1 | -64,562,113 |
Let's try dividing by 4:
64,562,113 ÷ 4 = 16,140,528.25
If the quotient is a whole number, then 4 and 16,140,528.25 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 | 64,562,113 | |
| -1 | 64,562,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 89 | 623 | 979 | 6,853 | 9,421 | 65,947 | 103,631 | 725,417 | 838,469 | 5,869,283 | 9,223,159 | 64,562,113 |
| -1 | -7 | -11 | -77 | -89 | -623 | -979 | -6,853 | -9,421 | -65,947 | -103,631 | -725,417 | -838,469 | -5,869,283 | -9,223,159 | -64,562,113 |
