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 64,628,011, 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 | 64,628,011 | |
| -1 | -64,628,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,628,011.
Example:
1 x 64,628,011 = 64,628,011
and
-1 x -64,628,011 = 64,628,011
Notice both answers equal 64,628,011
With that explanation out of the way, let's continue. Next, we take the number 64,628,011 and divide it by 2:
64,628,011 ÷ 2 = 32,314,005.5
If the quotient is a whole number, then 2 and 32,314,005.5 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 | 64,628,011 | |
| -1 | -64,628,011 |
Now, we try dividing 64,628,011 by 3:
64,628,011 ÷ 3 = 21,542,670.3333
If the quotient is a whole number, then 3 and 21,542,670.3333 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 | 64,628,011 | |
| -1 | -64,628,011 |
Let's try dividing by 4:
64,628,011 ÷ 4 = 16,157,002.75
If the quotient is a whole number, then 4 and 16,157,002.75 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 | 64,628,011 | |
| -1 | 64,628,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 43 | 49 | 259 | 301 | 829 | 1,591 | 1,813 | 2,107 | 5,803 | 11,137 | 30,673 | 35,647 | 40,621 | 77,959 | 214,711 | 249,529 | 1,318,939 | 1,502,977 | 1,746,703 | 9,232,573 | 64,628,011 |
| -1 | -7 | -37 | -43 | -49 | -259 | -301 | -829 | -1,591 | -1,813 | -2,107 | -5,803 | -11,137 | -30,673 | -35,647 | -40,621 | -77,959 | -214,711 | -249,529 | -1,318,939 | -1,502,977 | -1,746,703 | -9,232,573 | -64,628,011 |
