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 761,064,337, 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 | 761,064,337 | |
| -1 | -761,064,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,064,337.
Example:
1 x 761,064,337 = 761,064,337
and
-1 x -761,064,337 = 761,064,337
Notice both answers equal 761,064,337
With that explanation out of the way, let's continue. Next, we take the number 761,064,337 and divide it by 2:
761,064,337 ÷ 2 = 380,532,168.5
If the quotient is a whole number, then 2 and 380,532,168.5 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 | 761,064,337 | |
| -1 | -761,064,337 |
Now, we try dividing 761,064,337 by 3:
761,064,337 ÷ 3 = 253,688,112.3333
If the quotient is a whole number, then 3 and 253,688,112.3333 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 | 761,064,337 | |
| -1 | -761,064,337 |
Let's try dividing by 4:
761,064,337 ÷ 4 = 190,266,084.25
If the quotient is a whole number, then 4 and 190,266,084.25 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 | 761,064,337 | |
| -1 | 761,064,337 |
If you did it right, you will end up with this table:
| 1 | 11 | 139 | 409 | 1,217 | 1,529 | 4,499 | 13,387 | 56,851 | 169,163 | 497,753 | 625,361 | 1,860,793 | 5,475,283 | 69,187,667 | 761,064,337 |
| -1 | -11 | -139 | -409 | -1,217 | -1,529 | -4,499 | -13,387 | -56,851 | -169,163 | -497,753 | -625,361 | -1,860,793 | -5,475,283 | -69,187,667 | -761,064,337 |
