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 70,636,765, 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 | 70,636,765 | |
| -1 | -70,636,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,636,765.
Example:
1 x 70,636,765 = 70,636,765
and
-1 x -70,636,765 = 70,636,765
Notice both answers equal 70,636,765
With that explanation out of the way, let's continue. Next, we take the number 70,636,765 and divide it by 2:
70,636,765 ÷ 2 = 35,318,382.5
If the quotient is a whole number, then 2 and 35,318,382.5 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 | 70,636,765 | |
| -1 | -70,636,765 |
Now, we try dividing 70,636,765 by 3:
70,636,765 ÷ 3 = 23,545,588.3333
If the quotient is a whole number, then 3 and 23,545,588.3333 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 | 70,636,765 | |
| -1 | -70,636,765 |
Let's try dividing by 4:
70,636,765 ÷ 4 = 17,659,191.25
If the quotient is a whole number, then 4 and 17,659,191.25 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 | 70,636,765 | |
| -1 | 70,636,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 127 | 173 | 635 | 643 | 865 | 3,215 | 21,971 | 81,661 | 109,855 | 111,239 | 408,305 | 556,195 | 14,127,353 | 70,636,765 |
| -1 | -5 | -127 | -173 | -635 | -643 | -865 | -3,215 | -21,971 | -81,661 | -109,855 | -111,239 | -408,305 | -556,195 | -14,127,353 | -70,636,765 |
