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 140,502,263, 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 | 140,502,263 | |
| -1 | -140,502,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,502,263.
Example:
1 x 140,502,263 = 140,502,263
and
-1 x -140,502,263 = 140,502,263
Notice both answers equal 140,502,263
With that explanation out of the way, let's continue. Next, we take the number 140,502,263 and divide it by 2:
140,502,263 ÷ 2 = 70,251,131.5
If the quotient is a whole number, then 2 and 70,251,131.5 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 | 140,502,263 | |
| -1 | -140,502,263 |
Now, we try dividing 140,502,263 by 3:
140,502,263 ÷ 3 = 46,834,087.6667
If the quotient is a whole number, then 3 and 46,834,087.6667 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 | 140,502,263 | |
| -1 | -140,502,263 |
Let's try dividing by 4:
140,502,263 ÷ 4 = 35,125,565.75
If the quotient is a whole number, then 4 and 35,125,565.75 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 | 140,502,263 | |
| -1 | 140,502,263 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 193 | 229 | 289 | 2,123 | 2,519 | 3,179 | 3,281 | 3,893 | 36,091 | 42,823 | 44,197 | 55,777 | 66,181 | 486,167 | 613,547 | 727,991 | 751,349 | 8,264,839 | 12,772,933 | 140,502,263 |
| -1 | -11 | -17 | -187 | -193 | -229 | -289 | -2,123 | -2,519 | -3,179 | -3,281 | -3,893 | -36,091 | -42,823 | -44,197 | -55,777 | -66,181 | -486,167 | -613,547 | -727,991 | -751,349 | -8,264,839 | -12,772,933 | -140,502,263 |
