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 167,750,615, 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 | 167,750,615 | |
| -1 | -167,750,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,750,615.
Example:
1 x 167,750,615 = 167,750,615
and
-1 x -167,750,615 = 167,750,615
Notice both answers equal 167,750,615
With that explanation out of the way, let's continue. Next, we take the number 167,750,615 and divide it by 2:
167,750,615 ÷ 2 = 83,875,307.5
If the quotient is a whole number, then 2 and 83,875,307.5 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 | 167,750,615 | |
| -1 | -167,750,615 |
Now, we try dividing 167,750,615 by 3:
167,750,615 ÷ 3 = 55,916,871.6667
If the quotient is a whole number, then 3 and 55,916,871.6667 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 | 167,750,615 | |
| -1 | -167,750,615 |
Let's try dividing by 4:
167,750,615 ÷ 4 = 41,937,653.75
If the quotient is a whole number, then 4 and 41,937,653.75 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 | 167,750,615 | |
| -1 | 167,750,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 691 | 2,111 | 3,455 | 10,555 | 15,893 | 48,553 | 79,465 | 242,765 | 1,458,701 | 7,293,505 | 33,550,123 | 167,750,615 |
| -1 | -5 | -23 | -115 | -691 | -2,111 | -3,455 | -10,555 | -15,893 | -48,553 | -79,465 | -242,765 | -1,458,701 | -7,293,505 | -33,550,123 | -167,750,615 |
