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 71,002,547, 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 | 71,002,547 | |
| -1 | -71,002,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,002,547.
Example:
1 x 71,002,547 = 71,002,547
and
-1 x -71,002,547 = 71,002,547
Notice both answers equal 71,002,547
With that explanation out of the way, let's continue. Next, we take the number 71,002,547 and divide it by 2:
71,002,547 ÷ 2 = 35,501,273.5
If the quotient is a whole number, then 2 and 35,501,273.5 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 | 71,002,547 | |
| -1 | -71,002,547 |
Now, we try dividing 71,002,547 by 3:
71,002,547 ÷ 3 = 23,667,515.6667
If the quotient is a whole number, then 3 and 23,667,515.6667 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 | 71,002,547 | |
| -1 | -71,002,547 |
Let's try dividing by 4:
71,002,547 ÷ 4 = 17,750,636.75
If the quotient is a whole number, then 4 and 17,750,636.75 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 | 71,002,547 | |
| -1 | 71,002,547 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 59 | 77 | 413 | 649 | 4,543 | 15,629 | 109,403 | 171,919 | 922,111 | 1,203,433 | 6,454,777 | 10,143,221 | 71,002,547 |
| -1 | -7 | -11 | -59 | -77 | -413 | -649 | -4,543 | -15,629 | -109,403 | -171,919 | -922,111 | -1,203,433 | -6,454,777 | -10,143,221 | -71,002,547 |
