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 70,111,739, 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 | 70,111,739 | |
| -1 | -70,111,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,111,739.
Example:
1 x 70,111,739 = 70,111,739
and
-1 x -70,111,739 = 70,111,739
Notice both answers equal 70,111,739
With that explanation out of the way, let's continue. Next, we take the number 70,111,739 and divide it by 2:
70,111,739 ÷ 2 = 35,055,869.5
If the quotient is a whole number, then 2 and 35,055,869.5 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 | 70,111,739 | |
| -1 | -70,111,739 |
Now, we try dividing 70,111,739 by 3:
70,111,739 ÷ 3 = 23,370,579.6667
If the quotient is a whole number, then 3 and 23,370,579.6667 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 | 70,111,739 | |
| -1 | -70,111,739 |
Let's try dividing by 4:
70,111,739 ÷ 4 = 17,527,934.75
If the quotient is a whole number, then 4 and 17,527,934.75 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 | 70,111,739 | |
| -1 | 70,111,739 |
If you did it right, you will end up with this table:
| 1 | 31 | 53 | 139 | 307 | 1,643 | 4,309 | 7,367 | 9,517 | 16,271 | 42,673 | 228,377 | 504,401 | 1,322,863 | 2,261,669 | 70,111,739 |
| -1 | -31 | -53 | -139 | -307 | -1,643 | -4,309 | -7,367 | -9,517 | -16,271 | -42,673 | -228,377 | -504,401 | -1,322,863 | -2,261,669 | -70,111,739 |
