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 35,422,387, 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 | 35,422,387 | |
| -1 | -35,422,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,422,387.
Example:
1 x 35,422,387 = 35,422,387
and
-1 x -35,422,387 = 35,422,387
Notice both answers equal 35,422,387
With that explanation out of the way, let's continue. Next, we take the number 35,422,387 and divide it by 2:
35,422,387 ÷ 2 = 17,711,193.5
If the quotient is a whole number, then 2 and 17,711,193.5 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 | 35,422,387 | |
| -1 | -35,422,387 |
Now, we try dividing 35,422,387 by 3:
35,422,387 ÷ 3 = 11,807,462.3333
If the quotient is a whole number, then 3 and 11,807,462.3333 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 | 35,422,387 | |
| -1 | -35,422,387 |
Let's try dividing by 4:
35,422,387 ÷ 4 = 8,855,596.75
If the quotient is a whole number, then 4 and 8,855,596.75 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 | 35,422,387 | |
| -1 | 35,422,387 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 143 | 847 | 1,001 | 1,573 | 3,217 | 11,011 | 22,519 | 35,387 | 41,821 | 247,709 | 292,747 | 389,257 | 460,031 | 2,724,799 | 3,220,217 | 5,060,341 | 35,422,387 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -143 | -847 | -1,001 | -1,573 | -3,217 | -11,011 | -22,519 | -35,387 | -41,821 | -247,709 | -292,747 | -389,257 | -460,031 | -2,724,799 | -3,220,217 | -5,060,341 | -35,422,387 |
