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 221,113,333, 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 | 221,113,333 | |
| -1 | -221,113,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 221,113,333.
Example:
1 x 221,113,333 = 221,113,333
and
-1 x -221,113,333 = 221,113,333
Notice both answers equal 221,113,333
With that explanation out of the way, let's continue. Next, we take the number 221,113,333 and divide it by 2:
221,113,333 ÷ 2 = 110,556,666.5
If the quotient is a whole number, then 2 and 110,556,666.5 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 | 221,113,333 | |
| -1 | -221,113,333 |
Now, we try dividing 221,113,333 by 3:
221,113,333 ÷ 3 = 73,704,444.3333
If the quotient is a whole number, then 3 and 73,704,444.3333 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 | 221,113,333 | |
| -1 | -221,113,333 |
Let's try dividing by 4:
221,113,333 ÷ 4 = 55,278,333.25
If the quotient is a whole number, then 4 and 55,278,333.25 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 | 221,113,333 | |
| -1 | 221,113,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 49 | 67 | 329 | 469 | 1,433 | 2,303 | 3,149 | 3,283 | 10,031 | 22,043 | 67,351 | 70,217 | 96,011 | 154,301 | 471,457 | 672,077 | 3,300,199 | 4,512,517 | 4,704,539 | 31,587,619 | 221,113,333 |
| -1 | -7 | -47 | -49 | -67 | -329 | -469 | -1,433 | -2,303 | -3,149 | -3,283 | -10,031 | -22,043 | -67,351 | -70,217 | -96,011 | -154,301 | -471,457 | -672,077 | -3,300,199 | -4,512,517 | -4,704,539 | -31,587,619 | -221,113,333 |
