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 537,668,677, 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 | 537,668,677 | |
| -1 | -537,668,677 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 537,668,677.
Example:
1 x 537,668,677 = 537,668,677
and
-1 x -537,668,677 = 537,668,677
Notice both answers equal 537,668,677
With that explanation out of the way, let's continue. Next, we take the number 537,668,677 and divide it by 2:
537,668,677 ÷ 2 = 268,834,338.5
If the quotient is a whole number, then 2 and 268,834,338.5 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 | 537,668,677 | |
| -1 | -537,668,677 |
Now, we try dividing 537,668,677 by 3:
537,668,677 ÷ 3 = 179,222,892.3333
If the quotient is a whole number, then 3 and 179,222,892.3333 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 | 537,668,677 | |
| -1 | -537,668,677 |
Let's try dividing by 4:
537,668,677 ÷ 4 = 134,417,169.25
If the quotient is a whole number, then 4 and 134,417,169.25 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 | 537,668,677 | |
| -1 | 537,668,677 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 2,093 | 256,889 | 1,798,223 | 3,339,557 | 5,908,447 | 23,376,899 | 41,359,129 | 76,809,811 | 537,668,677 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -2,093 | -256,889 | -1,798,223 | -3,339,557 | -5,908,447 | -23,376,899 | -41,359,129 | -76,809,811 | -537,668,677 |
