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 71,300,047, 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 | 71,300,047 | |
| -1 | -71,300,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,300,047.
Example:
1 x 71,300,047 = 71,300,047
and
-1 x -71,300,047 = 71,300,047
Notice both answers equal 71,300,047
With that explanation out of the way, let's continue. Next, we take the number 71,300,047 and divide it by 2:
71,300,047 ÷ 2 = 35,650,023.5
If the quotient is a whole number, then 2 and 35,650,023.5 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 | 71,300,047 | |
| -1 | -71,300,047 |
Now, we try dividing 71,300,047 by 3:
71,300,047 ÷ 3 = 23,766,682.3333
If the quotient is a whole number, then 3 and 23,766,682.3333 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 | 71,300,047 | |
| -1 | -71,300,047 |
Let's try dividing by 4:
71,300,047 ÷ 4 = 17,825,011.75
If the quotient is a whole number, then 4 and 17,825,011.75 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 | 71,300,047 | |
| -1 | 71,300,047 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 173 | 637 | 647 | 1,211 | 2,249 | 4,529 | 8,411 | 8,477 | 15,743 | 31,703 | 58,877 | 110,201 | 111,931 | 412,139 | 783,517 | 1,455,103 | 5,484,619 | 10,185,721 | 71,300,047 |
| -1 | -7 | -13 | -49 | -91 | -173 | -637 | -647 | -1,211 | -2,249 | -4,529 | -8,411 | -8,477 | -15,743 | -31,703 | -58,877 | -110,201 | -111,931 | -412,139 | -783,517 | -1,455,103 | -5,484,619 | -10,185,721 | -71,300,047 |
