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 202,625,143, 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 | 202,625,143 | |
| -1 | -202,625,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,625,143.
Example:
1 x 202,625,143 = 202,625,143
and
-1 x -202,625,143 = 202,625,143
Notice both answers equal 202,625,143
With that explanation out of the way, let's continue. Next, we take the number 202,625,143 and divide it by 2:
202,625,143 ÷ 2 = 101,312,571.5
If the quotient is a whole number, then 2 and 101,312,571.5 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 | 202,625,143 | |
| -1 | -202,625,143 |
Now, we try dividing 202,625,143 by 3:
202,625,143 ÷ 3 = 67,541,714.3333
If the quotient is a whole number, then 3 and 67,541,714.3333 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 | 202,625,143 | |
| -1 | -202,625,143 |
Let's try dividing by 4:
202,625,143 ÷ 4 = 50,656,285.75
If the quotient is a whole number, then 4 and 50,656,285.75 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 | 202,625,143 | |
| -1 | 202,625,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 89 | 97 | 479 | 623 | 679 | 3,353 | 4,361 | 4,753 | 8,633 | 23,471 | 42,631 | 46,463 | 60,431 | 298,417 | 325,241 | 423,017 | 2,088,919 | 2,276,687 | 4,135,207 | 28,946,449 | 202,625,143 |
| -1 | -7 | -49 | -89 | -97 | -479 | -623 | -679 | -3,353 | -4,361 | -4,753 | -8,633 | -23,471 | -42,631 | -46,463 | -60,431 | -298,417 | -325,241 | -423,017 | -2,088,919 | -2,276,687 | -4,135,207 | -28,946,449 | -202,625,143 |
