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 130,602,199, 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 | 130,602,199 | |
| -1 | -130,602,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,602,199.
Example:
1 x 130,602,199 = 130,602,199
and
-1 x -130,602,199 = 130,602,199
Notice both answers equal 130,602,199
With that explanation out of the way, let's continue. Next, we take the number 130,602,199 and divide it by 2:
130,602,199 ÷ 2 = 65,301,099.5
If the quotient is a whole number, then 2 and 65,301,099.5 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 | 130,602,199 | |
| -1 | -130,602,199 |
Now, we try dividing 130,602,199 by 3:
130,602,199 ÷ 3 = 43,534,066.3333
If the quotient is a whole number, then 3 and 43,534,066.3333 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 | 130,602,199 | |
| -1 | -130,602,199 |
Let's try dividing by 4:
130,602,199 ÷ 4 = 32,650,549.75
If the quotient is a whole number, then 4 and 32,650,549.75 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 | 130,602,199 | |
| -1 | 130,602,199 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 421 | 487 | 637 | 2,947 | 3,409 | 5,473 | 6,331 | 20,629 | 23,863 | 38,311 | 44,317 | 205,027 | 268,177 | 310,219 | 1,435,189 | 2,665,351 | 10,046,323 | 18,657,457 | 130,602,199 |
| -1 | -7 | -13 | -49 | -91 | -421 | -487 | -637 | -2,947 | -3,409 | -5,473 | -6,331 | -20,629 | -23,863 | -38,311 | -44,317 | -205,027 | -268,177 | -310,219 | -1,435,189 | -2,665,351 | -10,046,323 | -18,657,457 | -130,602,199 |
