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 factors of larger numbers. To find the factors of the number 137,661,316, it is easiest to start from the outside in. Here's what we mean:
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.
| 1 | 137,661,316 |
Next, we take the number 137,661,316 and divide it by 2.
In this case, 137,661,316 ÷ 2 = 68,830,658
If the quotient is a whole number, then 2 and 68,830,658 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
| 1 | 2 | 68,830,658 | 137,661,316 |
Now, we try dividing 137,661,316 by 3.
137,661,316 ÷ 3 = 45,887,105.3333
If the quotient is a whole number, then 3 and 45,887,105.3333 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 2 | 68,830,658 | 137,661,316 |
Let's try dividing by 4.
137,661,316 ÷ 4 = 34,415,329
If the quotient is a whole number, then 4 and 34,415,329 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
Here is what our table should look like at this step:
| 1 | 2 | 4 | 34,415,329 | 68,830,658 | 137,661,316 |
We keep dividing by the next largest number, in this case the number 5. If the quotient of 137,661,316 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.
Keep dividing by the next highest number until you cannot divide anymore.
What you will end up with is this table:
| 1 | 2 | 4 | 13 | 26 | 52 | 169 | 338 | 676 | 203,641 | 407,282 | 814,564 | 2,647,333 | 5,294,666 | 10,589,332 | 34,415,329 | 68,830,658 | 137,661,316 |
All of the numbers in the table above can be evenly divided into the number 137,661,316.
Finally, for your reference, here are all of the divisor combinations of the number 137,661,316:
1 x 1376613162 x 688306584 x 3441532913 x 1058933226 x 529466652 x 2647333169 x 814564338 x 407282676 x 203641
