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 140,410,039, 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 | 140,410,039 | |
| -1 | -140,410,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,410,039.
Example:
1 x 140,410,039 = 140,410,039
and
-1 x -140,410,039 = 140,410,039
Notice both answers equal 140,410,039
With that explanation out of the way, let's continue. Next, we take the number 140,410,039 and divide it by 2:
140,410,039 ÷ 2 = 70,205,019.5
If the quotient is a whole number, then 2 and 70,205,019.5 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 | 140,410,039 | |
| -1 | -140,410,039 |
Now, we try dividing 140,410,039 by 3:
140,410,039 ÷ 3 = 46,803,346.3333
If the quotient is a whole number, then 3 and 46,803,346.3333 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 | 140,410,039 | |
| -1 | -140,410,039 |
Let's try dividing by 4:
140,410,039 ÷ 4 = 35,102,509.75
If the quotient is a whole number, then 4 and 35,102,509.75 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 | 140,410,039 | |
| -1 | 140,410,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 337 | 539 | 773 | 2,359 | 3,707 | 5,411 | 8,503 | 16,513 | 25,949 | 37,877 | 59,521 | 181,643 | 260,501 | 416,647 | 1,823,507 | 2,865,511 | 12,764,549 | 20,058,577 | 140,410,039 |
| -1 | -7 | -11 | -49 | -77 | -337 | -539 | -773 | -2,359 | -3,707 | -5,411 | -8,503 | -16,513 | -25,949 | -37,877 | -59,521 | -181,643 | -260,501 | -416,647 | -1,823,507 | -2,865,511 | -12,764,549 | -20,058,577 | -140,410,039 |
