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 153,746,461, 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 | 153,746,461 | |
| -1 | -153,746,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,746,461.
Example:
1 x 153,746,461 = 153,746,461
and
-1 x -153,746,461 = 153,746,461
Notice both answers equal 153,746,461
With that explanation out of the way, let's continue. Next, we take the number 153,746,461 and divide it by 2:
153,746,461 ÷ 2 = 76,873,230.5
If the quotient is a whole number, then 2 and 76,873,230.5 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 | 153,746,461 | |
| -1 | -153,746,461 |
Now, we try dividing 153,746,461 by 3:
153,746,461 ÷ 3 = 51,248,820.3333
If the quotient is a whole number, then 3 and 51,248,820.3333 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 | 153,746,461 | |
| -1 | -153,746,461 |
Let's try dividing by 4:
153,746,461 ÷ 4 = 38,436,615.25
If the quotient is a whole number, then 4 and 38,436,615.25 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 | 153,746,461 | |
| -1 | 153,746,461 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 83 | 209 | 913 | 1,577 | 8,863 | 17,347 | 97,493 | 168,397 | 735,629 | 1,852,367 | 8,091,919 | 13,976,951 | 153,746,461 |
| -1 | -11 | -19 | -83 | -209 | -913 | -1,577 | -8,863 | -17,347 | -97,493 | -168,397 | -735,629 | -1,852,367 | -8,091,919 | -13,976,951 | -153,746,461 |
