Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
How do you work out the lcm when there are indices?
It is the same as finding the LCM of two numbers that have been expressed as a product of their prime factors except that you need to use the highest index for each prime factor.
How can you determine whether the LCM of two numbers is the product of the numbers or is less than the product if the numbers?
By finding out whether they have any factors in common. If the only factor they have in common is 1, the LCM will be their product. If they have more factors in common, their LCM will be less than their product.
How would finding the Lcm help you when dividing items into equal groups?
It doesn't. You need common factors for that, not common multiples.
How can knowing the GCF and LCM help you when you add subtract and multiply fractions?
Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.
Why find factor?
Finding factors is the first step in finding the GCF and the LCM. They will help you to reduce fractions, or add and subtract them.
What is the LCM step by step of 2 and 5?
Step One: Multiply them together. Step Two: Call that the LCM.
What could be the second step in finding the sum negative thirteen plus negative dwindling using a number line with intervals at every integer?
The second step depends on what was done as the first step!
What is the first step in finding LCM of tow or more numbers?
Writing the numbers down. If you've already done that, then find their prime factorizations.
What could be the second step in finding the sum using a number line with intervals at every integer?
the answer is - 0
What is the LCM of 351014?
Finding the LCM requires two or more numbers. The LCM of a single number is itself.
What is the LCM of 91815?
The LCM of one number is itself. Finding the LCM involves two or more numbers.
What is the LCM of 493575?
The LCM of one number is itself. Finding the LCM requires two or more numbers.
When do you use GCF and LCM?
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors
What is the LCM of 353933?
The LCM of a single number is itself. Finding the LCM requires two or more numbers to solve.
What can be done do about sulfur dioxide pollution?
Finding/using fuels with a lower sulphur content would be a large step. Technology to capture sulphur dioxide from combustion byproducts would be a second large step. Finding an economical use for for the captured byproducts would make the second step much more attractive to those who produce sulphur dioxide.
What are the steps in subtracting dissimilar fractions?
Step I: Find the LCM of the denominators. Step II: Find equivalent fraction such that the new denominators are the LCM. Step III: Carry out the subtraction on these numerators to arrive at the new numerator. Step IV: New denominator = LCM. Step V: Simplify the fraction.
