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 140,157,199, 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 | 140,157,199 | |
| -1 | -140,157,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,157,199.
Example:
1 x 140,157,199 = 140,157,199
and
-1 x -140,157,199 = 140,157,199
Notice both answers equal 140,157,199
With that explanation out of the way, let's continue. Next, we take the number 140,157,199 and divide it by 2:
140,157,199 ÷ 2 = 70,078,599.5
If the quotient is a whole number, then 2 and 70,078,599.5 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 | 140,157,199 | |
| -1 | -140,157,199 |
Now, we try dividing 140,157,199 by 3:
140,157,199 ÷ 3 = 46,719,066.3333
If the quotient is a whole number, then 3 and 46,719,066.3333 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 | 140,157,199 | |
| -1 | -140,157,199 |
Let's try dividing by 4:
140,157,199 ÷ 4 = 35,039,299.75
If the quotient is a whole number, then 4 and 35,039,299.75 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 | 140,157,199 | |
| -1 | 140,157,199 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 61 | 91 | 427 | 637 | 793 | 2,989 | 3,607 | 5,551 | 25,249 | 38,857 | 46,891 | 176,743 | 220,027 | 328,237 | 1,540,189 | 2,297,659 | 2,860,351 | 10,781,323 | 20,022,457 | 140,157,199 |
| -1 | -7 | -13 | -49 | -61 | -91 | -427 | -637 | -793 | -2,989 | -3,607 | -5,551 | -25,249 | -38,857 | -46,891 | -176,743 | -220,027 | -328,237 | -1,540,189 | -2,297,659 | -2,860,351 | -10,781,323 | -20,022,457 | -140,157,199 |
