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 537,410,203, 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 | 537,410,203 | |
| -1 | -537,410,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 537,410,203.
Example:
1 x 537,410,203 = 537,410,203
and
-1 x -537,410,203 = 537,410,203
Notice both answers equal 537,410,203
With that explanation out of the way, let's continue. Next, we take the number 537,410,203 and divide it by 2:
537,410,203 ÷ 2 = 268,705,101.5
If the quotient is a whole number, then 2 and 268,705,101.5 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 | 537,410,203 | |
| -1 | -537,410,203 |
Now, we try dividing 537,410,203 by 3:
537,410,203 ÷ 3 = 179,136,734.3333
If the quotient is a whole number, then 3 and 179,136,734.3333 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 | 537,410,203 | |
| -1 | -537,410,203 |
Let's try dividing by 4:
537,410,203 ÷ 4 = 134,352,550.75
If the quotient is a whole number, then 4 and 134,352,550.75 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 | 537,410,203 | |
| -1 | 537,410,203 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 31 | 253 | 341 | 713 | 7,843 | 68,521 | 753,731 | 1,575,983 | 2,124,151 | 17,335,813 | 23,365,661 | 48,855,473 | 537,410,203 |
| -1 | -11 | -23 | -31 | -253 | -341 | -713 | -7,843 | -68,521 | -753,731 | -1,575,983 | -2,124,151 | -17,335,813 | -23,365,661 | -48,855,473 | -537,410,203 |
