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 70,667,065, 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 | 70,667,065 | |
| -1 | -70,667,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,667,065.
Example:
1 x 70,667,065 = 70,667,065
and
-1 x -70,667,065 = 70,667,065
Notice both answers equal 70,667,065
With that explanation out of the way, let's continue. Next, we take the number 70,667,065 and divide it by 2:
70,667,065 ÷ 2 = 35,333,532.5
If the quotient is a whole number, then 2 and 35,333,532.5 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 | 70,667,065 | |
| -1 | -70,667,065 |
Now, we try dividing 70,667,065 by 3:
70,667,065 ÷ 3 = 23,555,688.3333
If the quotient is a whole number, then 3 and 23,555,688.3333 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 | 70,667,065 | |
| -1 | -70,667,065 |
Let's try dividing by 4:
70,667,065 ÷ 4 = 17,666,766.25
If the quotient is a whole number, then 4 and 17,666,766.25 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 | 70,667,065 | |
| -1 | 70,667,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 211 | 245 | 1,055 | 1,367 | 1,477 | 6,835 | 7,385 | 9,569 | 10,339 | 47,845 | 51,695 | 66,983 | 288,437 | 334,915 | 1,442,185 | 2,019,059 | 10,095,295 | 14,133,413 | 70,667,065 |
| -1 | -5 | -7 | -35 | -49 | -211 | -245 | -1,055 | -1,367 | -1,477 | -6,835 | -7,385 | -9,569 | -10,339 | -47,845 | -51,695 | -66,983 | -288,437 | -334,915 | -1,442,185 | -2,019,059 | -10,095,295 | -14,133,413 | -70,667,065 |
