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 762,544,111, 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 | 762,544,111 | |
| -1 | -762,544,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 762,544,111.
Example:
1 x 762,544,111 = 762,544,111
and
-1 x -762,544,111 = 762,544,111
Notice both answers equal 762,544,111
With that explanation out of the way, let's continue. Next, we take the number 762,544,111 and divide it by 2:
762,544,111 ÷ 2 = 381,272,055.5
If the quotient is a whole number, then 2 and 381,272,055.5 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 | 762,544,111 | |
| -1 | -762,544,111 |
Now, we try dividing 762,544,111 by 3:
762,544,111 ÷ 3 = 254,181,370.3333
If the quotient is a whole number, then 3 and 254,181,370.3333 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 | 762,544,111 | |
| -1 | -762,544,111 |
Let's try dividing by 4:
762,544,111 ÷ 4 = 190,636,027.75
If the quotient is a whole number, then 4 and 190,636,027.75 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 | 762,544,111 | |
| -1 | 762,544,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 151 | 587 | 1,057 | 1,229 | 4,109 | 8,603 | 88,637 | 185,579 | 620,459 | 721,423 | 1,299,053 | 5,049,961 | 108,934,873 | 762,544,111 |
| -1 | -7 | -151 | -587 | -1,057 | -1,229 | -4,109 | -8,603 | -88,637 | -185,579 | -620,459 | -721,423 | -1,299,053 | -5,049,961 | -108,934,873 | -762,544,111 |
