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 134,571,073, 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 | 134,571,073 | |
| -1 | -134,571,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,571,073.
Example:
1 x 134,571,073 = 134,571,073
and
-1 x -134,571,073 = 134,571,073
Notice both answers equal 134,571,073
With that explanation out of the way, let's continue. Next, we take the number 134,571,073 and divide it by 2:
134,571,073 ÷ 2 = 67,285,536.5
If the quotient is a whole number, then 2 and 67,285,536.5 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 | 134,571,073 | |
| -1 | -134,571,073 |
Now, we try dividing 134,571,073 by 3:
134,571,073 ÷ 3 = 44,857,024.3333
If the quotient is a whole number, then 3 and 44,857,024.3333 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 | 134,571,073 | |
| -1 | -134,571,073 |
Let's try dividing by 4:
134,571,073 ÷ 4 = 33,642,768.25
If the quotient is a whole number, then 4 and 33,642,768.25 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 | 134,571,073 | |
| -1 | 134,571,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 109 | 763 | 1,417 | 9,919 | 13,567 | 94,969 | 176,371 | 1,234,597 | 1,478,803 | 10,351,621 | 19,224,439 | 134,571,073 |
| -1 | -7 | -13 | -91 | -109 | -763 | -1,417 | -9,919 | -13,567 | -94,969 | -176,371 | -1,234,597 | -1,478,803 | -10,351,621 | -19,224,439 | -134,571,073 |
