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 731,766,139, 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 | 731,766,139 | |
| -1 | -731,766,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 731,766,139.
Example:
1 x 731,766,139 = 731,766,139
and
-1 x -731,766,139 = 731,766,139
Notice both answers equal 731,766,139
With that explanation out of the way, let's continue. Next, we take the number 731,766,139 and divide it by 2:
731,766,139 ÷ 2 = 365,883,069.5
If the quotient is a whole number, then 2 and 365,883,069.5 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 | 731,766,139 | |
| -1 | -731,766,139 |
Now, we try dividing 731,766,139 by 3:
731,766,139 ÷ 3 = 243,922,046.3333
If the quotient is a whole number, then 3 and 243,922,046.3333 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 | 731,766,139 | |
| -1 | -731,766,139 |
Let's try dividing by 4:
731,766,139 ÷ 4 = 182,941,534.75
If the quotient is a whole number, then 4 and 182,941,534.75 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 | 731,766,139 | |
| -1 | 731,766,139 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 751 | 4,409 | 9,763 | 12,767 | 57,317 | 74,953 | 165,971 | 974,389 | 3,311,159 | 43,045,067 | 56,289,703 | 731,766,139 |
| -1 | -13 | -17 | -221 | -751 | -4,409 | -9,763 | -12,767 | -57,317 | -74,953 | -165,971 | -974,389 | -3,311,159 | -43,045,067 | -56,289,703 | -731,766,139 |
