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 36,357,139, 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 | 36,357,139 | |
| -1 | -36,357,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,357,139.
Example:
1 x 36,357,139 = 36,357,139
and
-1 x -36,357,139 = 36,357,139
Notice both answers equal 36,357,139
With that explanation out of the way, let's continue. Next, we take the number 36,357,139 and divide it by 2:
36,357,139 ÷ 2 = 18,178,569.5
If the quotient is a whole number, then 2 and 18,178,569.5 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 | 36,357,139 | |
| -1 | -36,357,139 |
Now, we try dividing 36,357,139 by 3:
36,357,139 ÷ 3 = 12,119,046.3333
If the quotient is a whole number, then 3 and 12,119,046.3333 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 | 36,357,139 | |
| -1 | -36,357,139 |
Let's try dividing by 4:
36,357,139 ÷ 4 = 9,089,284.75
If the quotient is a whole number, then 4 and 9,089,284.75 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 | 36,357,139 | |
| -1 | 36,357,139 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 169 | 421 | 511 | 949 | 1,183 | 2,947 | 5,473 | 6,643 | 12,337 | 30,733 | 38,311 | 71,149 | 86,359 | 215,131 | 399,529 | 498,043 | 2,796,703 | 5,193,877 | 36,357,139 |
| -1 | -7 | -13 | -73 | -91 | -169 | -421 | -511 | -949 | -1,183 | -2,947 | -5,473 | -6,643 | -12,337 | -30,733 | -38,311 | -71,149 | -86,359 | -215,131 | -399,529 | -498,043 | -2,796,703 | -5,193,877 | -36,357,139 |
