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 537,162,685, 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 | 537,162,685 | |
| -1 | -537,162,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 537,162,685.
Example:
1 x 537,162,685 = 537,162,685
and
-1 x -537,162,685 = 537,162,685
Notice both answers equal 537,162,685
With that explanation out of the way, let's continue. Next, we take the number 537,162,685 and divide it by 2:
537,162,685 ÷ 2 = 268,581,342.5
If the quotient is a whole number, then 2 and 268,581,342.5 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 | 537,162,685 | |
| -1 | -537,162,685 |
Now, we try dividing 537,162,685 by 3:
537,162,685 ÷ 3 = 179,054,228.3333
If the quotient is a whole number, then 3 and 179,054,228.3333 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 | 537,162,685 | |
| -1 | -537,162,685 |
Let's try dividing by 4:
537,162,685 ÷ 4 = 134,290,671.25
If the quotient is a whole number, then 4 and 134,290,671.25 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 | 537,162,685 | |
| -1 | 537,162,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 901 | 4,505 | 119,237 | 596,185 | 2,027,029 | 6,319,561 | 10,135,145 | 31,597,805 | 107,432,537 | 537,162,685 |
| -1 | -5 | -17 | -53 | -85 | -265 | -901 | -4,505 | -119,237 | -596,185 | -2,027,029 | -6,319,561 | -10,135,145 | -31,597,805 | -107,432,537 | -537,162,685 |
