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 485,751,053, 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 | 485,751,053 | |
| -1 | -485,751,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 485,751,053.
Example:
1 x 485,751,053 = 485,751,053
and
-1 x -485,751,053 = 485,751,053
Notice both answers equal 485,751,053
With that explanation out of the way, let's continue. Next, we take the number 485,751,053 and divide it by 2:
485,751,053 ÷ 2 = 242,875,526.5
If the quotient is a whole number, then 2 and 242,875,526.5 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 | 485,751,053 | |
| -1 | -485,751,053 |
Now, we try dividing 485,751,053 by 3:
485,751,053 ÷ 3 = 161,917,017.6667
If the quotient is a whole number, then 3 and 161,917,017.6667 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 | 485,751,053 | |
| -1 | -485,751,053 |
Let's try dividing by 4:
485,751,053 ÷ 4 = 121,437,763.25
If the quotient is a whole number, then 4 and 121,437,763.25 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 | 485,751,053 | |
| -1 | 485,751,053 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 359 | 661 | 2,047 | 8,257 | 15,203 | 31,951 | 58,829 | 237,299 | 734,873 | 1,353,067 | 5,457,877 | 21,119,611 | 485,751,053 |
| -1 | -23 | -89 | -359 | -661 | -2,047 | -8,257 | -15,203 | -31,951 | -58,829 | -237,299 | -734,873 | -1,353,067 | -5,457,877 | -21,119,611 | -485,751,053 |
