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 700,406,875, 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 | 700,406,875 | |
| -1 | -700,406,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 700,406,875.
Example:
1 x 700,406,875 = 700,406,875
and
-1 x -700,406,875 = 700,406,875
Notice both answers equal 700,406,875
With that explanation out of the way, let's continue. Next, we take the number 700,406,875 and divide it by 2:
700,406,875 ÷ 2 = 350,203,437.5
If the quotient is a whole number, then 2 and 350,203,437.5 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 | 700,406,875 | |
| -1 | -700,406,875 |
Now, we try dividing 700,406,875 by 3:
700,406,875 ÷ 3 = 233,468,958.3333
If the quotient is a whole number, then 3 and 233,468,958.3333 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 | 700,406,875 | |
| -1 | -700,406,875 |
Let's try dividing by 4:
700,406,875 ÷ 4 = 175,101,718.75
If the quotient is a whole number, then 4 and 175,101,718.75 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 | 700,406,875 | |
| -1 | 700,406,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 625 | 875 | 4,375 | 160,093 | 800,465 | 1,120,651 | 4,002,325 | 5,603,255 | 20,011,625 | 28,016,275 | 100,058,125 | 140,081,375 | 700,406,875 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -625 | -875 | -4,375 | -160,093 | -800,465 | -1,120,651 | -4,002,325 | -5,603,255 | -20,011,625 | -28,016,275 | -100,058,125 | -140,081,375 | -700,406,875 |
