Solution Factors are numbers that can divide without remainder. Factors of 721 721/1 = 721         gives remainder 0 and so are divisible by 1 721/7 = 103         gives remainder 0 and so are divisible by 7 721/103 = 7         gives remainder 0 and so are divisible by 103 721/721 = 1         gives remainder 0 and so are divisible by 721 Factors of 724 724/1 = 724         gives remainder 0 and so are divisible by 1 724/2 = 362         gives remainder 0 and so are divisible by 2 724/4 = 181         gives remainder 0 and so are divisible by 4 724/181 = 4         gives remainder 0 and so are divisible by 181 724/362 = 2         gives remainder 0 and so are divisible by 362 724/724 = 1         gives remainder 0 and so are divisible by 724 Factors of 726 726/1 = 726         gives remainder 0 and so are divisible by 1 726/2 = 363         gives remainder 0 and so are divisible by 2 726/3 = 242         gives remainder 0 and so are divisible by 3 726/6 = 121         gives remainder 0 and so are divisible by 6 726/11 = 66         gives remainder 0 and so are divisible by 11 726/22 = 33         gives remainder 0 and so are divisible by 22 726/33 = 22         gives remainder 0 and so are divisible by 33 726/66 = 11         gives remainder 0 and so are divisible by 66 726/121 = 6         gives remainder 0 and so are divisible by 121 726/242 = 3         gives remainder 0 and so are divisible by 242 726/363 = 2         gives remainder 0 and so are divisible by 363 726/726 = 1         gives remainder 0 and so are divisible by 726

Converting to factors of 721,724,726

We get factors of 721,724,726 numbers by finding numbers that can be multiplied together to equal the target number being converted.

This means numbers that can divide 721,724,726 without remainders. So first number to consider is 1 and 721,724,726

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.
