Lets say you ran a plant that used special screws to hold a motor together. The screws come in packages of 8, and the motors come in packages of 10. You don't want a lot of extra screws around, because they are very expensive. So you wonder- at what point do the screws and motors match up in packages of 8 and 10? That way you can order them in even amounts. The answer is 40, because 5 x 8 and 4 x 10 both = 40.

What's the difference between a greatest common factor and a least common multiple?
Difference Between GCF and LCM. The Greatest Common Factor (or the GCF) is the greatest real number shared between two integers. ... On the other hand, the Lowest Common Multiple (or LCM) is the integer shared by two numbers that can be divided by both numbers
What are two pairs of numbers that have 10 as their least common multiple?
Well, darling, any pair of numbers that are multiples of 10 would work just fine. For example, 10 and 20, or 30 and 10. As long as 10 is the smallest number that both pairs can be evenly divided by, you're good to go. Math can be a real hoot sometimes, can't it?
Can you always find the least common multiple of 2 numbers by multiplying them together?
No, that will not always work. in the case for some numbers it will work. for example 3 * 4 = 12. it works here. however if you do that for 30 and 20, you will get 600. the real lowest common multiple is 60. so it does not always work.
What are some real life applications of gcf and LCM?
Those are commonly used for working with fractions. You need the least common multiple to find a common denominator, for adding or subtracting fractions. And after doing some manipulations with fractions, you need the greatest common factor to simplify the fractions.Now, whether this is sufficiently "real-life" for you, is another issue. Depending on the career you choose, you many need to work with fractions on a daily basis, or you may hardly ever need them.
What numbers are divisible by 3 4 and 5?
Well, honey, the numbers that are divisible by 3, 4, and 5 are called multiples of the least common multiple of 3, 4, and 5, which is 60. So, any number that is a multiple of 60 will be divisible by 3, 4, and 5. Math can be a real party pooper sometimes, but that's just how the cookie crumbles.
Least common multiple of 14 and 49?
unlike the answer before, they did it wrong. The real answer is 98.98
What is a Real life situation using LCM?
Adding or subtracting fractions requires the use of a common multiple. It is rare that the LEAST common multiple is required - it is useful to keep the numbers small and manageable.
What is the definition of greatest common multiple the real definition?
There is no definition - real or otherwise - because there can be no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
What is a real world problem where you would have to find the least common multiple?
Any time you add two unlike fractions (carpenters do this a lot) the process of finding the common denominator is the same as the LCM.
What's the difference between a greatest common factor and a least common multiple?
Difference Between GCF and LCM. The Greatest Common Factor (or the GCF) is the greatest real number shared between two integers. ... On the other hand, the Lowest Common Multiple (or LCM) is the integer shared by two numbers that can be divided by both numbers

In real life what can least common multiple do?
In a non-academic, practical setting the LCM is used when unlike fractions are added or subtracted, like when a carpenter has to add measurements of eights and sixteenths.
What are two real-world problems that can be solved using the GCM of two numbers?
There are none because there is no such thing as a Greatest Common Multiple (GCM). If {a, b, c, ... x} is any set of integers, then a*b*c*...*x is a common multiple. Then twice that number is also a common multiple and is greater. And then, twice THAT number is a common multiple and greater still. It is easy to show that this process can go on for ever and so there is no such thing as a GCM.
Write a real word problems which it be helpful to find the least common factor?
It's never helpful to find the least common factor. The least common factor of any set of integers is 1.
What are the greatest common factors that could happen in the real world?
The greatest common factors that are able to happen in the real world are as follows: 1: Nothing 2: Nothing and 3: Nothing
Are demontors real in Harry Potter?
Yes, in Harry Potter's world (witch is a fantasy world, remember!) dementors are real. Heliopaths, for example, are not real, at least their existence is not proved yet.
What is greatest common factor of 16 28 and 32?
Oh, dude, the greatest common factor of 16, 28, and 32 is 4. It's like the superhero that swoops in and saves the day by being the biggest number that divides evenly into all three of those numbers. So yeah, 4 is the real MVP in this math problem.
