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 140,541,355, 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 | 140,541,355 | |
| -1 | -140,541,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,541,355.
Example:
1 x 140,541,355 = 140,541,355
and
-1 x -140,541,355 = 140,541,355
Notice both answers equal 140,541,355
With that explanation out of the way, let's continue. Next, we take the number 140,541,355 and divide it by 2:
140,541,355 ÷ 2 = 70,270,677.5
If the quotient is a whole number, then 2 and 70,270,677.5 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 | 140,541,355 | |
| -1 | -140,541,355 |
Now, we try dividing 140,541,355 by 3:
140,541,355 ÷ 3 = 46,847,118.3333
If the quotient is a whole number, then 3 and 46,847,118.3333 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 | 140,541,355 | |
| -1 | -140,541,355 |
Let's try dividing by 4:
140,541,355 ÷ 4 = 35,135,338.75
If the quotient is a whole number, then 4 and 35,135,338.75 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 | 140,541,355 | |
| -1 | 140,541,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 167 | 185 | 835 | 4,549 | 6,179 | 22,745 | 30,895 | 168,313 | 759,683 | 841,565 | 3,798,415 | 28,108,271 | 140,541,355 |
| -1 | -5 | -37 | -167 | -185 | -835 | -4,549 | -6,179 | -22,745 | -30,895 | -168,313 | -759,683 | -841,565 | -3,798,415 | -28,108,271 | -140,541,355 |
