Solution Factors are numbers that can divide without remainder. Factors of 7122 7122/1 = 7122 gives remainder 0 and so are divisible by 17122/2 = 3561 gives remainder 0 and so are divisible by 2 7122/3 = 2374 gives remainder 0 and so are divisible by 3 7122/6 = 1187 gives remainder 0 and so are divisible by 6 7122/1187 = 6 gives remainder 0 and so are divisible by 1187 7122/2374 = 3 gives remainder 0 and so are divisible by 2374 7122/3561 = 2 gives remainder 0 and so are divisible by 3561 7122/7122 = 1 gives remainder 0 and so are divisible by 7122 Factors of 7125 7125/1 = 7125 gives remainder 0 and so are divisible by 17125/3 = 2375 gives remainder 0 and so are divisible by 3 7125/5 = 1425 gives remainder 0 and so are divisible by 5 7125/15 = 475 gives remainder 0 and so are divisible by 15 7125/19 = 375 gives remainder 0 and so are divisible by 19 7125/25 = 285 gives remainder 0 and so are divisible by 25 7125/57 = 125 gives remainder 0 and so are divisible by 57 7125/75 = 95 gives remainder 0 and so are divisible by 75 7125/95 = 75 gives remainder 0 and so are divisible by 95 7125/125 = 57 gives remainder 0 and so are divisible by 125 7125/285 = 25 gives remainder 0 and so are divisible by 285 7125/375 = 19 gives remainder 0 and so are divisible by 375 7125/475 = 15 gives remainder 0 and so are divisible by 475 7125/1425 = 5 gives remainder 0 and so are divisible by 1425 7125/2375 = 3 gives remainder 0 and so are divisible by 2375 7125/7125 = 1 gives remainder 0 and so are divisible by 7125 Factors of 7127 7127/1 = 7127 gives remainder 0 and so are divisible by 17127/7127 = 1 gives remainder 0 and so are divisible by 7127 |
Converting to factors of 7122,7125,7127
We get factors of 7122,7125,7127 numbers by finding numbers that can be multiplied together to equal the target number being converted.
This means numbers that can divide 7122,7125,7127 without remainders. So first number to consider is 1 and 7122,7125,7127
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.

Other number conversions to consider
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.
