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 70,614,643, 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 | 70,614,643 | |
| -1 | -70,614,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,614,643.
Example:
1 x 70,614,643 = 70,614,643
and
-1 x -70,614,643 = 70,614,643
Notice both answers equal 70,614,643
With that explanation out of the way, let's continue. Next, we take the number 70,614,643 and divide it by 2:
70,614,643 ÷ 2 = 35,307,321.5
If the quotient is a whole number, then 2 and 35,307,321.5 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 | 70,614,643 | |
| -1 | -70,614,643 |
Now, we try dividing 70,614,643 by 3:
70,614,643 ÷ 3 = 23,538,214.3333
If the quotient is a whole number, then 3 and 23,538,214.3333 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 | 70,614,643 | |
| -1 | -70,614,643 |
Let's try dividing by 4:
70,614,643 ÷ 4 = 17,653,660.75
If the quotient is a whole number, then 4 and 17,653,660.75 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 | 70,614,643 | |
| -1 | 70,614,643 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 337 | 443 | 473 | 3,707 | 4,873 | 14,491 | 19,049 | 149,291 | 159,401 | 209,539 | 1,642,201 | 6,419,513 | 70,614,643 |
| -1 | -11 | -43 | -337 | -443 | -473 | -3,707 | -4,873 | -14,491 | -19,049 | -149,291 | -159,401 | -209,539 | -1,642,201 | -6,419,513 | -70,614,643 |
