Solution Factors are numbers that can divide without remainder. Factors of 100123 100123/1 = 100123 gives remainder 0 and so are divisible by 1100123/59 = 1697 gives remainder 0 and so are divisible by 59 100123/1697 = 59 gives remainder 0 and so are divisible by 1697 100123/100123 = 1 gives remainder 0 and so are divisible by 100123 Factors of 100125 100125/1 = 100125 gives remainder 0 and so are divisible by 1100125/3 = 33375 gives remainder 0 and so are divisible by 3 100125/5 = 20025 gives remainder 0 and so are divisible by 5 100125/9 = 11125 gives remainder 0 and so are divisible by 9 100125/15 = 6675 gives remainder 0 and so are divisible by 15 100125/25 = 4005 gives remainder 0 and so are divisible by 25 100125/45 = 2225 gives remainder 0 and so are divisible by 45 100125/75 = 1335 gives remainder 0 and so are divisible by 75 100125/89 = 1125 gives remainder 0 and so are divisible by 89 100125/125 = 801 gives remainder 0 and so are divisible by 125 100125/225 = 445 gives remainder 0 and so are divisible by 225 100125/267 = 375 gives remainder 0 and so are divisible by 267 100125/375 = 267 gives remainder 0 and so are divisible by 375 100125/445 = 225 gives remainder 0 and so are divisible by 445 100125/801 = 125 gives remainder 0 and so are divisible by 801 100125/1125 = 89 gives remainder 0 and so are divisible by 1125 100125/1335 = 75 gives remainder 0 and so are divisible by 1335 100125/2225 = 45 gives remainder 0 and so are divisible by 2225 100125/4005 = 25 gives remainder 0 and so are divisible by 4005 100125/6675 = 15 gives remainder 0 and so are divisible by 6675 100125/11125 = 9 gives remainder 0 and so are divisible by 11125 100125/20025 = 5 gives remainder 0 and so are divisible by 20025 100125/33375 = 3 gives remainder 0 and so are divisible by 33375 100125/100125 = 1 gives remainder 0 and so are divisible by 100125 |
Converting to factors of 100123,100125
We get factors of 100123,100125 numbers by finding numbers that can be multiplied together to equal the target number being converted.
This means numbers that can divide 100123,100125 without remainders. So first number to consider is 1 and 100123,100125
Getting factors is done by diving the number with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors.

Factors are the numbers you multiply to get another number. For instance, the factors of 25 are 5 and 5, because 5×5 = 25. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4. A number that can only be factored as 1 times itself is called "prime". The first few primes are 2, 3, 5, 7, 11, and 13. The number 1 is not regarded as a prime, and is usually not included in factorizations, because 1 goes into everything. (The number 1 is a bit boring in this context, so it gets ignored.
By the way, there are some divisibility rules that can help you find the numbers to divide by. There are many divisibility rules, but the simplest to use are these: If the number is even, then it's divisible by 2. If the number's digits sum to a number that's divisible by 3, then the number itself is divisible by 3. If the number ends with a 0 or a 5, then it's divisible by 5.
Of course, if the number is divisible twice by 2, then it's divisible by 4; if it's divisible by 2 and by 3, then it's divisible by 6; and if it's divisible twice by 3 (or if the sum of the digits is divisible by 9), then it's divisible by 9. But since you're finding the factorization, you don't really care about these non-prime divisibility rules. There is a rule for divisibility by 7, but it's complicated enough that it's probably easier to just do the division on your calculator and see if it comes out even.
If you run out of small numbers and you are not done factoring, then keep trying bigger and bigger whole numbers (9, 14, 17, 20, 23, etc) until you find number that can divide without remainder. For example, 13 is a factor of 52 because 13 divides exactly into 52 (52 ÷ 13 = 4 leaving no remainder). The complete list of factors of 52 is: 1, 2, 4, 13, 26, and 52 (all these divide exactly into 52). If your number doesn't divide in, then the only potential divisors are bigger numbers. Since the square of your number is bigger than the number.
