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 700,171,045, 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 | 700,171,045 | |
| -1 | -700,171,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 700,171,045.
Example:
1 x 700,171,045 = 700,171,045
and
-1 x -700,171,045 = 700,171,045
Notice both answers equal 700,171,045
With that explanation out of the way, let's continue. Next, we take the number 700,171,045 and divide it by 2:
700,171,045 ÷ 2 = 350,085,522.5
If the quotient is a whole number, then 2 and 350,085,522.5 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 | 700,171,045 | |
| -1 | -700,171,045 |
Now, we try dividing 700,171,045 by 3:
700,171,045 ÷ 3 = 233,390,348.3333
If the quotient is a whole number, then 3 and 233,390,348.3333 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 | 700,171,045 | |
| -1 | -700,171,045 |
Let's try dividing by 4:
700,171,045 ÷ 4 = 175,042,761.25
If the quotient is a whole number, then 4 and 175,042,761.25 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 | 700,171,045 | |
| -1 | 700,171,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 408,263 | 2,041,315 | 2,857,841 | 14,289,205 | 20,004,887 | 100,024,435 | 140,034,209 | 700,171,045 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -408,263 | -2,041,315 | -2,857,841 | -14,289,205 | -20,004,887 | -100,024,435 | -140,034,209 | -700,171,045 |
