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 30,714,355, 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 | 30,714,355 | |
| -1 | -30,714,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,714,355.
Example:
1 x 30,714,355 = 30,714,355
and
-1 x -30,714,355 = 30,714,355
Notice both answers equal 30,714,355
With that explanation out of the way, let's continue. Next, we take the number 30,714,355 and divide it by 2:
30,714,355 ÷ 2 = 15,357,177.5
If the quotient is a whole number, then 2 and 15,357,177.5 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 | 30,714,355 | |
| -1 | -30,714,355 |
Now, we try dividing 30,714,355 by 3:
30,714,355 ÷ 3 = 10,238,118.3333
If the quotient is a whole number, then 3 and 10,238,118.3333 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 | 30,714,355 | |
| -1 | -30,714,355 |
Let's try dividing by 4:
30,714,355 ÷ 4 = 7,678,588.75
If the quotient is a whole number, then 4 and 7,678,588.75 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 | 30,714,355 | |
| -1 | 30,714,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 46,187 | 230,935 | 323,309 | 877,553 | 1,616,545 | 4,387,765 | 6,142,871 | 30,714,355 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -46,187 | -230,935 | -323,309 | -877,553 | -1,616,545 | -4,387,765 | -6,142,871 | -30,714,355 |
