You might use the array to store the results, since a number may be made up of several prime factors. As soon as you find a prime factor, save the result to the array, and continue looking for additional factors. If you want all factors, not just prime factors, the principle is the same; you can store the results of your calculations to an array.

What is the LCM of 27 45 81?
To find the LCM of numbers you first need to break them down into their prime factors. In this case: 27=3x3x3 45=5x3x3 81=3x3x3x3 The next step is to disregard any duplicates when there are common prime factors. All numbers use two 3s so we can disregard 4 of them. Two numbers use an additional 3 so we can disregard 1 of them. This leaves us with: 5,3,3,3,3 Find the product of all of these numbers: 5x3x3x3=405 And that gives us the LCM. So the LCM of 27, 45, and 81 is 405.
What two factors of 882 add up to -63?

What are the square numbers up to 1000?
They are the squares of the numbers 1 to 31. Use a calculator to find them.
What arrays do you use to find the factors of 27?
The factors of 27 are 1, 3, 9 and 27. You could use 1 row of 27 blocks or 3 rows of 9 blocks.
Name two smaller arrays you can use to find the product of 8x6?
name two smaller arrays you can use to find the product
How you use multiplication to find the factors of a number?
You make a line of numbers in this case factors.
How do you use arrays or area models to find factor pairs?
I am not sure what you mean with "area models". As for an array, one simple way to use it is to try out different factors in a loop; every time you find a factor, you write the factor to the next array element.
What is the GCF of 28 using prime factors?
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
How can you find a GCF?
Example: GCF of 6 and 12= 2 Example 2: GCF of 54 and 6=9 List all the factors of the numbers you use, then if the numbers you have when you list the factors have the same number in both sets of numbers, that is your GCF
What function would you use to find the mean in a Microsoft Excel document?
The AVERAGE function returns the average (arithmetic mean) of the numbers provided.=AVERAGE(number1,number2,...number_n)number1, number2, ... number_n are numeric values. They can be numbers, named ranges, arrays, or references to numbers. You can enter up to 30 values.
Did you use the factors of 100 to find the factors of 200 is so how?
The factors of 100 are included in the factors of 200, but I did not use one to find the other.
What is the algorithm of LCM of more than 3 numbers?
If you use methods based on prime factors, it is the same whether you have 2, 3, or more numbers: find all the factors that occur in any of your numbers. If you use a method based on Euclid's Algorithm (that is, lcm(a, b) = a x b / gcf(a, b), where you find the gcf with Euclid's Algorithm), then you can find the lcm for two numbers at a time. For example, to get the lcm of four numbers, find the lcm of the first two, then the lcm of the result and the third number, than the lcm of the result and the fourth number.
How do you use prime factorization find the GCF of two numbers?
The first step of finding the GCF is to split the numbers into their prime factors. For instance, if I wanted to find the GCF of 30 and 105, I would split these up into: 30 = 2x3x5 105 = 3x5x7 The next step would be to identify any common prime factors. In this case both numbers have 3 and 5 as prime factors, so these would be the ones we use. To find the GCF, you simply multiply these two numbers together: 3x5 = 15 So 15 would be the GCF in that case.
What do you call the numbers you use to multiply?
Factors OR multiplicands.
Why do you use antenna arrays?
To improve the signal :)
