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 768,859, 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 | 768,859 | |
| -1 | -768,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 768,859.
Example:
1 x 768,859 = 768,859
and
-1 x -768,859 = 768,859
Notice both answers equal 768,859
With that explanation out of the way, let's continue. Next, we take the number 768,859 and divide it by 2:
768,859 ÷ 2 = 384,429.5
If the quotient is a whole number, then 2 and 384,429.5 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 | 768,859 | |
| -1 | -768,859 |
Now, we try dividing 768,859 by 3:
768,859 ÷ 3 = 256,286.3333
If the quotient is a whole number, then 3 and 256,286.3333 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 | 768,859 | |
| -1 | -768,859 |
Let's try dividing by 4:
768,859 ÷ 4 = 192,214.75
If the quotient is a whole number, then 4 and 192,214.75 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 | 768,859 | |
| -1 | 768,859 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 49 | 71 | 91 | 119 | 221 | 497 | 637 | 833 | 923 | 1,207 | 1,547 | 3,479 | 6,461 | 8,449 | 10,829 | 15,691 | 45,227 | 59,143 | 109,837 | 768,859 |
| -1 | -7 | -13 | -17 | -49 | -71 | -91 | -119 | -221 | -497 | -637 | -833 | -923 | -1,207 | -1,547 | -3,479 | -6,461 | -8,449 | -10,829 | -15,691 | -45,227 | -59,143 | -109,837 | -768,859 |
