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 40,570,537, 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 | 40,570,537 | |
| -1 | -40,570,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,570,537.
Example:
1 x 40,570,537 = 40,570,537
and
-1 x -40,570,537 = 40,570,537
Notice both answers equal 40,570,537
With that explanation out of the way, let's continue. Next, we take the number 40,570,537 and divide it by 2:
40,570,537 ÷ 2 = 20,285,268.5
If the quotient is a whole number, then 2 and 20,285,268.5 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 | 40,570,537 | |
| -1 | -40,570,537 |
Now, we try dividing 40,570,537 by 3:
40,570,537 ÷ 3 = 13,523,512.3333
If the quotient is a whole number, then 3 and 13,523,512.3333 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 | 40,570,537 | |
| -1 | -40,570,537 |
Let's try dividing by 4:
40,570,537 ÷ 4 = 10,142,634.25
If the quotient is a whole number, then 4 and 10,142,634.25 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 | 40,570,537 | |
| -1 | 40,570,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 37 | 163 | 217 | 259 | 961 | 1,141 | 1,147 | 5,053 | 6,031 | 6,727 | 8,029 | 35,371 | 35,557 | 42,217 | 156,643 | 186,961 | 248,899 | 1,096,501 | 1,308,727 | 5,795,791 | 40,570,537 |
| -1 | -7 | -31 | -37 | -163 | -217 | -259 | -961 | -1,141 | -1,147 | -5,053 | -6,031 | -6,727 | -8,029 | -35,371 | -35,557 | -42,217 | -156,643 | -186,961 | -248,899 | -1,096,501 | -1,308,727 | -5,795,791 | -40,570,537 |
