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 7,464,785, 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 | 7,464,785 | |
| -1 | -7,464,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,464,785.
Example:
1 x 7,464,785 = 7,464,785
and
-1 x -7,464,785 = 7,464,785
Notice both answers equal 7,464,785
With that explanation out of the way, let's continue. Next, we take the number 7,464,785 and divide it by 2:
7,464,785 ÷ 2 = 3,732,392.5
If the quotient is a whole number, then 2 and 3,732,392.5 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 | 7,464,785 | |
| -1 | -7,464,785 |
Now, we try dividing 7,464,785 by 3:
7,464,785 ÷ 3 = 2,488,261.6667
If the quotient is a whole number, then 3 and 2,488,261.6667 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 | 7,464,785 | |
| -1 | -7,464,785 |
Let's try dividing by 4:
7,464,785 ÷ 4 = 1,866,196.25
If the quotient is a whole number, then 4 and 1,866,196.25 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 | 7,464,785 | |
| -1 | 7,464,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 901 | 1,657 | 4,505 | 8,285 | 28,169 | 87,821 | 140,845 | 439,105 | 1,492,957 | 7,464,785 |
| -1 | -5 | -17 | -53 | -85 | -265 | -901 | -1,657 | -4,505 | -8,285 | -28,169 | -87,821 | -140,845 | -439,105 | -1,492,957 | -7,464,785 |
