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 301,554,143, 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 | 301,554,143 | |
| -1 | -301,554,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 301,554,143.
Example:
1 x 301,554,143 = 301,554,143
and
-1 x -301,554,143 = 301,554,143
Notice both answers equal 301,554,143
With that explanation out of the way, let's continue. Next, we take the number 301,554,143 and divide it by 2:
301,554,143 ÷ 2 = 150,777,071.5
If the quotient is a whole number, then 2 and 150,777,071.5 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 | 301,554,143 | |
| -1 | -301,554,143 |
Now, we try dividing 301,554,143 by 3:
301,554,143 ÷ 3 = 100,518,047.6667
If the quotient is a whole number, then 3 and 100,518,047.6667 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 | 301,554,143 | |
| -1 | -301,554,143 |
Let's try dividing by 4:
301,554,143 ÷ 4 = 75,388,535.75
If the quotient is a whole number, then 4 and 75,388,535.75 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 | 301,554,143 | |
| -1 | 301,554,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 121 | 187 | 341 | 527 | 2,057 | 3,751 | 4,729 | 5,797 | 52,019 | 63,767 | 80,393 | 146,599 | 572,209 | 884,323 | 1,612,589 | 2,492,183 | 9,727,553 | 17,738,479 | 27,414,013 | 301,554,143 |
| -1 | -11 | -17 | -31 | -121 | -187 | -341 | -527 | -2,057 | -3,751 | -4,729 | -5,797 | -52,019 | -63,767 | -80,393 | -146,599 | -572,209 | -884,323 | -1,612,589 | -2,492,183 | -9,727,553 | -17,738,479 | -27,414,013 | -301,554,143 |
