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 145,033,889, 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 | 145,033,889 | |
| -1 | -145,033,889 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,033,889.
Example:
1 x 145,033,889 = 145,033,889
and
-1 x -145,033,889 = 145,033,889
Notice both answers equal 145,033,889
With that explanation out of the way, let's continue. Next, we take the number 145,033,889 and divide it by 2:
145,033,889 ÷ 2 = 72,516,944.5
If the quotient is a whole number, then 2 and 72,516,944.5 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 | 145,033,889 | |
| -1 | -145,033,889 |
Now, we try dividing 145,033,889 by 3:
145,033,889 ÷ 3 = 48,344,629.6667
If the quotient is a whole number, then 3 and 48,344,629.6667 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 | 145,033,889 | |
| -1 | -145,033,889 |
Let's try dividing by 4:
145,033,889 ÷ 4 = 36,258,472.25
If the quotient is a whole number, then 4 and 36,258,472.25 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 | 145,033,889 | |
| -1 | 145,033,889 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 144,889 | 1,014,223 | 1,593,779 | 1,883,557 | 11,156,453 | 13,184,899 | 20,719,127 | 145,033,889 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -144,889 | -1,014,223 | -1,593,779 | -1,883,557 | -11,156,453 | -13,184,899 | -20,719,127 | -145,033,889 |
