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 202,351,045, 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 | 202,351,045 | |
| -1 | -202,351,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,351,045.
Example:
1 x 202,351,045 = 202,351,045
and
-1 x -202,351,045 = 202,351,045
Notice both answers equal 202,351,045
With that explanation out of the way, let's continue. Next, we take the number 202,351,045 and divide it by 2:
202,351,045 ÷ 2 = 101,175,522.5
If the quotient is a whole number, then 2 and 101,175,522.5 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 | 202,351,045 | |
| -1 | -202,351,045 |
Now, we try dividing 202,351,045 by 3:
202,351,045 ÷ 3 = 67,450,348.3333
If the quotient is a whole number, then 3 and 67,450,348.3333 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 | 202,351,045 | |
| -1 | -202,351,045 |
Let's try dividing by 4:
202,351,045 ÷ 4 = 50,587,761.25
If the quotient is a whole number, then 4 and 50,587,761.25 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 | 202,351,045 | |
| -1 | 202,351,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 163,847 | 819,235 | 2,130,011 | 3,113,093 | 10,650,055 | 15,565,465 | 40,470,209 | 202,351,045 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -163,847 | -819,235 | -2,130,011 | -3,113,093 | -10,650,055 | -15,565,465 | -40,470,209 | -202,351,045 |
