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 454,341,643, 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 | 454,341,643 | |
| -1 | -454,341,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 454,341,643.
Example:
1 x 454,341,643 = 454,341,643
and
-1 x -454,341,643 = 454,341,643
Notice both answers equal 454,341,643
With that explanation out of the way, let's continue. Next, we take the number 454,341,643 and divide it by 2:
454,341,643 ÷ 2 = 227,170,821.5
If the quotient is a whole number, then 2 and 227,170,821.5 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 | 454,341,643 | |
| -1 | -454,341,643 |
Now, we try dividing 454,341,643 by 3:
454,341,643 ÷ 3 = 151,447,214.3333
If the quotient is a whole number, then 3 and 151,447,214.3333 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 | 454,341,643 | |
| -1 | -454,341,643 |
Let's try dividing by 4:
454,341,643 ÷ 4 = 113,585,410.75
If the quotient is a whole number, then 4 and 113,585,410.75 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 | 454,341,643 | |
| -1 | 454,341,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 1,013 | 3,769 | 7,091 | 17,221 | 26,383 | 64,073 | 120,547 | 448,511 | 3,817,997 | 26,725,979 | 64,905,949 | 454,341,643 |
| -1 | -7 | -17 | -119 | -1,013 | -3,769 | -7,091 | -17,221 | -26,383 | -64,073 | -120,547 | -448,511 | -3,817,997 | -26,725,979 | -64,905,949 | -454,341,643 |
