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 40,023,445, 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 | 40,023,445 | |
| -1 | -40,023,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,023,445.
Example:
1 x 40,023,445 = 40,023,445
and
-1 x -40,023,445 = 40,023,445
Notice both answers equal 40,023,445
With that explanation out of the way, let's continue. Next, we take the number 40,023,445 and divide it by 2:
40,023,445 ÷ 2 = 20,011,722.5
If the quotient is a whole number, then 2 and 20,011,722.5 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 | 40,023,445 | |
| -1 | -40,023,445 |
Now, we try dividing 40,023,445 by 3:
40,023,445 ÷ 3 = 13,341,148.3333
If the quotient is a whole number, then 3 and 13,341,148.3333 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 | 40,023,445 | |
| -1 | -40,023,445 |
Let's try dividing by 4:
40,023,445 ÷ 4 = 10,005,861.25
If the quotient is a whole number, then 4 and 10,005,861.25 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 | 40,023,445 | |
| -1 | 40,023,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 2,695 | 14,851 | 74,255 | 103,957 | 163,361 | 519,785 | 727,699 | 816,805 | 1,143,527 | 3,638,495 | 5,717,635 | 8,004,689 | 40,023,445 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -2,695 | -14,851 | -74,255 | -103,957 | -163,361 | -519,785 | -727,699 | -816,805 | -1,143,527 | -3,638,495 | -5,717,635 | -8,004,689 | -40,023,445 |
