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 221,265,301, 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 | 221,265,301 | |
| -1 | -221,265,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 221,265,301.
Example:
1 x 221,265,301 = 221,265,301
and
-1 x -221,265,301 = 221,265,301
Notice both answers equal 221,265,301
With that explanation out of the way, let's continue. Next, we take the number 221,265,301 and divide it by 2:
221,265,301 ÷ 2 = 110,632,650.5
If the quotient is a whole number, then 2 and 110,632,650.5 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 | 221,265,301 | |
| -1 | -221,265,301 |
Now, we try dividing 221,265,301 by 3:
221,265,301 ÷ 3 = 73,755,100.3333
If the quotient is a whole number, then 3 and 73,755,100.3333 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 | 221,265,301 | |
| -1 | -221,265,301 |
Let's try dividing by 4:
221,265,301 ÷ 4 = 55,316,325.25
If the quotient is a whole number, then 4 and 55,316,325.25 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 | 221,265,301 | |
| -1 | 221,265,301 |
If you did it right, you will end up with this table:
| 1 | 53 | 83 | 179 | 281 | 4,399 | 9,487 | 14,857 | 14,893 | 23,323 | 50,299 | 787,421 | 1,236,119 | 2,665,847 | 4,174,817 | 221,265,301 |
| -1 | -53 | -83 | -179 | -281 | -4,399 | -9,487 | -14,857 | -14,893 | -23,323 | -50,299 | -787,421 | -1,236,119 | -2,665,847 | -4,174,817 | -221,265,301 |
