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 7,472,947, 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 | 7,472,947 | |
| -1 | -7,472,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,472,947.
Example:
1 x 7,472,947 = 7,472,947
and
-1 x -7,472,947 = 7,472,947
Notice both answers equal 7,472,947
With that explanation out of the way, let's continue. Next, we take the number 7,472,947 and divide it by 2:
7,472,947 ÷ 2 = 3,736,473.5
If the quotient is a whole number, then 2 and 3,736,473.5 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 | 7,472,947 | |
| -1 | -7,472,947 |
Now, we try dividing 7,472,947 by 3:
7,472,947 ÷ 3 = 2,490,982.3333
If the quotient is a whole number, then 3 and 2,490,982.3333 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 | 7,472,947 | |
| -1 | -7,472,947 |
Let's try dividing by 4:
7,472,947 ÷ 4 = 1,868,236.75
If the quotient is a whole number, then 4 and 1,868,236.75 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 | 7,472,947 | |
| -1 | 7,472,947 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 53 | 181 | 779 | 1,007 | 2,173 | 3,439 | 7,421 | 9,593 | 41,287 | 140,999 | 182,267 | 393,313 | 7,472,947 |
| -1 | -19 | -41 | -53 | -181 | -779 | -1,007 | -2,173 | -3,439 | -7,421 | -9,593 | -41,287 | -140,999 | -182,267 | -393,313 | -7,472,947 |
