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 70,583,117, 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 | 70,583,117 | |
| -1 | -70,583,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,583,117.
Example:
1 x 70,583,117 = 70,583,117
and
-1 x -70,583,117 = 70,583,117
Notice both answers equal 70,583,117
With that explanation out of the way, let's continue. Next, we take the number 70,583,117 and divide it by 2:
70,583,117 ÷ 2 = 35,291,558.5
If the quotient is a whole number, then 2 and 35,291,558.5 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 | 70,583,117 | |
| -1 | -70,583,117 |
Now, we try dividing 70,583,117 by 3:
70,583,117 ÷ 3 = 23,527,705.6667
If the quotient is a whole number, then 3 and 23,527,705.6667 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 | 70,583,117 | |
| -1 | -70,583,117 |
Let's try dividing by 4:
70,583,117 ÷ 4 = 17,645,779.25
If the quotient is a whole number, then 4 and 17,645,779.25 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 | 70,583,117 | |
| -1 | 70,583,117 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 97 | 797 | 913 | 1,067 | 8,051 | 8,767 | 66,151 | 77,309 | 88,561 | 727,661 | 850,399 | 6,416,647 | 70,583,117 |
| -1 | -11 | -83 | -97 | -797 | -913 | -1,067 | -8,051 | -8,767 | -66,151 | -77,309 | -88,561 | -727,661 | -850,399 | -6,416,647 | -70,583,117 |
