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 70,737,007, 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 | 70,737,007 | |
| -1 | -70,737,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,737,007.
Example:
1 x 70,737,007 = 70,737,007
and
-1 x -70,737,007 = 70,737,007
Notice both answers equal 70,737,007
With that explanation out of the way, let's continue. Next, we take the number 70,737,007 and divide it by 2:
70,737,007 ÷ 2 = 35,368,503.5
If the quotient is a whole number, then 2 and 35,368,503.5 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 | 70,737,007 | |
| -1 | -70,737,007 |
Now, we try dividing 70,737,007 by 3:
70,737,007 ÷ 3 = 23,579,002.3333
If the quotient is a whole number, then 3 and 23,579,002.3333 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 | 70,737,007 | |
| -1 | -70,737,007 |
Let's try dividing by 4:
70,737,007 ÷ 4 = 17,684,251.75
If the quotient is a whole number, then 4 and 17,684,251.75 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 | 70,737,007 | |
| -1 | 70,737,007 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 151 | 407 | 1,151 | 1,661 | 5,587 | 12,661 | 42,587 | 61,457 | 173,801 | 468,457 | 1,911,811 | 6,430,637 | 70,737,007 |
| -1 | -11 | -37 | -151 | -407 | -1,151 | -1,661 | -5,587 | -12,661 | -42,587 | -61,457 | -173,801 | -468,457 | -1,911,811 | -6,430,637 | -70,737,007 |
