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 702,905, 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 | 702,905 | |
| -1 | -702,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 702,905.
Example:
1 x 702,905 = 702,905
and
-1 x -702,905 = 702,905
Notice both answers equal 702,905
With that explanation out of the way, let's continue. Next, we take the number 702,905 and divide it by 2:
702,905 ÷ 2 = 351,452.5
If the quotient is a whole number, then 2 and 351,452.5 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 | 702,905 | |
| -1 | -702,905 |
Now, we try dividing 702,905 by 3:
702,905 ÷ 3 = 234,301.6667
If the quotient is a whole number, then 3 and 234,301.6667 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 | 702,905 | |
| -1 | -702,905 |
Let's try dividing by 4:
702,905 ÷ 4 = 175,726.25
If the quotient is a whole number, then 4 and 175,726.25 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 | 702,905 | |
| -1 | 702,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 151 | 245 | 665 | 755 | 931 | 1,057 | 2,869 | 4,655 | 5,285 | 7,399 | 14,345 | 20,083 | 36,995 | 100,415 | 140,581 | 702,905 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -151 | -245 | -665 | -755 | -931 | -1,057 | -2,869 | -4,655 | -5,285 | -7,399 | -14,345 | -20,083 | -36,995 | -100,415 | -140,581 | -702,905 |
