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 145,353,043, 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 | 145,353,043 | |
| -1 | -145,353,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,353,043.
Example:
1 x 145,353,043 = 145,353,043
and
-1 x -145,353,043 = 145,353,043
Notice both answers equal 145,353,043
With that explanation out of the way, let's continue. Next, we take the number 145,353,043 and divide it by 2:
145,353,043 ÷ 2 = 72,676,521.5
If the quotient is a whole number, then 2 and 72,676,521.5 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 | 145,353,043 | |
| -1 | -145,353,043 |
Now, we try dividing 145,353,043 by 3:
145,353,043 ÷ 3 = 48,451,014.3333
If the quotient is a whole number, then 3 and 48,451,014.3333 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 | 145,353,043 | |
| -1 | -145,353,043 |
Let's try dividing by 4:
145,353,043 ÷ 4 = 36,338,260.75
If the quotient is a whole number, then 4 and 36,338,260.75 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 | 145,353,043 | |
| -1 | 145,353,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 173 | 187 | 1,903 | 2,941 | 4,493 | 32,351 | 49,423 | 76,381 | 777,289 | 840,191 | 8,550,179 | 13,213,913 | 145,353,043 |
| -1 | -11 | -17 | -173 | -187 | -1,903 | -2,941 | -4,493 | -32,351 | -49,423 | -76,381 | -777,289 | -840,191 | -8,550,179 | -13,213,913 | -145,353,043 |
