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 762,187,429, 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 | 762,187,429 | |
| -1 | -762,187,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 762,187,429.
Example:
1 x 762,187,429 = 762,187,429
and
-1 x -762,187,429 = 762,187,429
Notice both answers equal 762,187,429
With that explanation out of the way, let's continue. Next, we take the number 762,187,429 and divide it by 2:
762,187,429 ÷ 2 = 381,093,714.5
If the quotient is a whole number, then 2 and 381,093,714.5 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 | 762,187,429 | |
| -1 | -762,187,429 |
Now, we try dividing 762,187,429 by 3:
762,187,429 ÷ 3 = 254,062,476.3333
If the quotient is a whole number, then 3 and 254,062,476.3333 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 | 762,187,429 | |
| -1 | -762,187,429 |
Let's try dividing by 4:
762,187,429 ÷ 4 = 190,546,857.25
If the quotient is a whole number, then 4 and 190,546,857.25 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 | 762,187,429 | |
| -1 | 762,187,429 |
If you did it right, you will end up with this table:
| 1 | 59 | 107 | 157 | 769 | 6,313 | 9,263 | 16,799 | 45,371 | 82,283 | 120,733 | 991,141 | 4,854,697 | 7,123,247 | 12,918,431 | 762,187,429 |
| -1 | -59 | -107 | -157 | -769 | -6,313 | -9,263 | -16,799 | -45,371 | -82,283 | -120,733 | -991,141 | -4,854,697 | -7,123,247 | -12,918,431 | -762,187,429 |
