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 130,772,143, 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 | 130,772,143 | |
| -1 | -130,772,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,772,143.
Example:
1 x 130,772,143 = 130,772,143
and
-1 x -130,772,143 = 130,772,143
Notice both answers equal 130,772,143
With that explanation out of the way, let's continue. Next, we take the number 130,772,143 and divide it by 2:
130,772,143 ÷ 2 = 65,386,071.5
If the quotient is a whole number, then 2 and 65,386,071.5 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 | 130,772,143 | |
| -1 | -130,772,143 |
Now, we try dividing 130,772,143 by 3:
130,772,143 ÷ 3 = 43,590,714.3333
If the quotient is a whole number, then 3 and 43,590,714.3333 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 | 130,772,143 | |
| -1 | -130,772,143 |
Let's try dividing by 4:
130,772,143 ÷ 4 = 32,693,035.75
If the quotient is a whole number, then 4 and 32,693,035.75 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 | 130,772,143 | |
| -1 | 130,772,143 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 241 | 541 | 1,003 | 4,097 | 9,197 | 14,219 | 31,919 | 130,381 | 241,723 | 542,623 | 2,216,477 | 7,692,479 | 130,772,143 |
| -1 | -17 | -59 | -241 | -541 | -1,003 | -4,097 | -9,197 | -14,219 | -31,919 | -130,381 | -241,723 | -542,623 | -2,216,477 | -7,692,479 | -130,772,143 |
