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 40,153,465, 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 | 40,153,465 | |
| -1 | -40,153,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,153,465.
Example:
1 x 40,153,465 = 40,153,465
and
-1 x -40,153,465 = 40,153,465
Notice both answers equal 40,153,465
With that explanation out of the way, let's continue. Next, we take the number 40,153,465 and divide it by 2:
40,153,465 ÷ 2 = 20,076,732.5
If the quotient is a whole number, then 2 and 20,076,732.5 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 | 40,153,465 | |
| -1 | -40,153,465 |
Now, we try dividing 40,153,465 by 3:
40,153,465 ÷ 3 = 13,384,488.3333
If the quotient is a whole number, then 3 and 13,384,488.3333 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 | 40,153,465 | |
| -1 | -40,153,465 |
Let's try dividing by 4:
40,153,465 ÷ 4 = 10,038,366.25
If the quotient is a whole number, then 4 and 10,038,366.25 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 | 40,153,465 | |
| -1 | 40,153,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 131 | 655 | 1,441 | 5,573 | 7,205 | 27,865 | 61,303 | 306,515 | 730,063 | 3,650,315 | 8,030,693 | 40,153,465 |
| -1 | -5 | -11 | -55 | -131 | -655 | -1,441 | -5,573 | -7,205 | -27,865 | -61,303 | -306,515 | -730,063 | -3,650,315 | -8,030,693 | -40,153,465 |
