If the first step is writing down the numbers, the second step is finding their prime factorizations.
Finding an LCM will help when you want to add and subtract fractions.
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.
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.
It doesn't. You need common factors for that, not common multiples.
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.
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.
Step One: Multiply them together. Step Two: Call that the LCM.
The second step depends on what was done as the first step!
Writing the numbers down. If you've already done that, then find their prime factorizations.
the answer is - 0
Finding the LCM requires two or more numbers. The LCM of a single number is itself.
The LCM of one number is itself. Finding the LCM involves two or more numbers.
The LCM of one number is itself. Finding the LCM requires two or more numbers.
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
The LCM of a single number is itself. Finding the LCM requires two or more numbers to solve.
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.
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.
