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 220,444,315, 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 | 220,444,315 | |
| -1 | -220,444,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,444,315.
Example:
1 x 220,444,315 = 220,444,315
and
-1 x -220,444,315 = 220,444,315
Notice both answers equal 220,444,315
With that explanation out of the way, let's continue. Next, we take the number 220,444,315 and divide it by 2:
220,444,315 ÷ 2 = 110,222,157.5
If the quotient is a whole number, then 2 and 110,222,157.5 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 | 220,444,315 | |
| -1 | -220,444,315 |
Now, we try dividing 220,444,315 by 3:
220,444,315 ÷ 3 = 73,481,438.3333
If the quotient is a whole number, then 3 and 73,481,438.3333 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 | 220,444,315 | |
| -1 | -220,444,315 |
Let's try dividing by 4:
220,444,315 ÷ 4 = 55,111,078.75
If the quotient is a whole number, then 4 and 55,111,078.75 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 | 220,444,315 | |
| -1 | 220,444,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 484,493 | 2,422,465 | 3,391,451 | 6,298,409 | 16,957,255 | 31,492,045 | 44,088,863 | 220,444,315 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -484,493 | -2,422,465 | -3,391,451 | -6,298,409 | -16,957,255 | -31,492,045 | -44,088,863 | -220,444,315 |
