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 40,694,465, 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 | 40,694,465 | |
| -1 | -40,694,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,694,465.
Example:
1 x 40,694,465 = 40,694,465
and
-1 x -40,694,465 = 40,694,465
Notice both answers equal 40,694,465
With that explanation out of the way, let's continue. Next, we take the number 40,694,465 and divide it by 2:
40,694,465 ÷ 2 = 20,347,232.5
If the quotient is a whole number, then 2 and 20,347,232.5 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 | 40,694,465 | |
| -1 | -40,694,465 |
Now, we try dividing 40,694,465 by 3:
40,694,465 ÷ 3 = 13,564,821.6667
If the quotient is a whole number, then 3 and 13,564,821.6667 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 | 40,694,465 | |
| -1 | -40,694,465 |
Let's try dividing by 4:
40,694,465 ÷ 4 = 10,173,616.25
If the quotient is a whole number, then 4 and 10,173,616.25 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 | 40,694,465 | |
| -1 | 40,694,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 661 | 1,759 | 3,305 | 4,627 | 8,795 | 12,313 | 23,135 | 61,565 | 1,162,699 | 5,813,495 | 8,138,893 | 40,694,465 |
| -1 | -5 | -7 | -35 | -661 | -1,759 | -3,305 | -4,627 | -8,795 | -12,313 | -23,135 | -61,565 | -1,162,699 | -5,813,495 | -8,138,893 | -40,694,465 |
