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 70,673,563, 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 | 70,673,563 | |
| -1 | -70,673,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,673,563.
Example:
1 x 70,673,563 = 70,673,563
and
-1 x -70,673,563 = 70,673,563
Notice both answers equal 70,673,563
With that explanation out of the way, let's continue. Next, we take the number 70,673,563 and divide it by 2:
70,673,563 ÷ 2 = 35,336,781.5
If the quotient is a whole number, then 2 and 35,336,781.5 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 | 70,673,563 | |
| -1 | -70,673,563 |
Now, we try dividing 70,673,563 by 3:
70,673,563 ÷ 3 = 23,557,854.3333
If the quotient is a whole number, then 3 and 23,557,854.3333 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 | 70,673,563 | |
| -1 | -70,673,563 |
Let's try dividing by 4:
70,673,563 ÷ 4 = 17,668,390.75
If the quotient is a whole number, then 4 and 17,668,390.75 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 | 70,673,563 | |
| -1 | 70,673,563 |
If you did it right, you will end up with this table:
| 1 | 59 | 61 | 73 | 269 | 3,599 | 4,307 | 4,453 | 15,871 | 16,409 | 19,637 | 262,727 | 968,131 | 1,158,583 | 1,197,857 | 70,673,563 |
| -1 | -59 | -61 | -73 | -269 | -3,599 | -4,307 | -4,453 | -15,871 | -16,409 | -19,637 | -262,727 | -968,131 | -1,158,583 | -1,197,857 | -70,673,563 |
