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 84,949,007, 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 | 84,949,007 | |
| -1 | -84,949,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,949,007.
Example:
1 x 84,949,007 = 84,949,007
and
-1 x -84,949,007 = 84,949,007
Notice both answers equal 84,949,007
With that explanation out of the way, let's continue. Next, we take the number 84,949,007 and divide it by 2:
84,949,007 ÷ 2 = 42,474,503.5
If the quotient is a whole number, then 2 and 42,474,503.5 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 | 84,949,007 | |
| -1 | -84,949,007 |
Now, we try dividing 84,949,007 by 3:
84,949,007 ÷ 3 = 28,316,335.6667
If the quotient is a whole number, then 3 and 28,316,335.6667 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 | 84,949,007 | |
| -1 | -84,949,007 |
Let's try dividing by 4:
84,949,007 ÷ 4 = 21,237,251.75
If the quotient is a whole number, then 4 and 21,237,251.75 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 | 84,949,007 | |
| -1 | 84,949,007 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 41 | 143 | 451 | 533 | 5,863 | 14,489 | 159,379 | 188,357 | 594,049 | 2,071,927 | 6,534,539 | 7,722,637 | 84,949,007 |
| -1 | -11 | -13 | -41 | -143 | -451 | -533 | -5,863 | -14,489 | -159,379 | -188,357 | -594,049 | -2,071,927 | -6,534,539 | -7,722,637 | -84,949,007 |
