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 70,666,939, 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 | 70,666,939 | |
| -1 | -70,666,939 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,666,939.
Example:
1 x 70,666,939 = 70,666,939
and
-1 x -70,666,939 = 70,666,939
Notice both answers equal 70,666,939
With that explanation out of the way, let's continue. Next, we take the number 70,666,939 and divide it by 2:
70,666,939 ÷ 2 = 35,333,469.5
If the quotient is a whole number, then 2 and 35,333,469.5 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 | 70,666,939 | |
| -1 | -70,666,939 |
Now, we try dividing 70,666,939 by 3:
70,666,939 ÷ 3 = 23,555,646.3333
If the quotient is a whole number, then 3 and 23,555,646.3333 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 | 70,666,939 | |
| -1 | -70,666,939 |
Let's try dividing by 4:
70,666,939 ÷ 4 = 17,666,734.75
If the quotient is a whole number, then 4 and 17,666,734.75 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 | 70,666,939 | |
| -1 | 70,666,939 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 71 | 203 | 497 | 2,059 | 4,903 | 14,413 | 34,321 | 142,187 | 348,113 | 995,309 | 2,436,791 | 10,095,277 | 70,666,939 |
| -1 | -7 | -29 | -71 | -203 | -497 | -2,059 | -4,903 | -14,413 | -34,321 | -142,187 | -348,113 | -995,309 | -2,436,791 | -10,095,277 | -70,666,939 |
