The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
Finding an LCM will help when you want to add and subtract fractions.
You don't. LCM and GCF (HCF) refer to whole numbers. You can find the LCM of two whole numbers that happen to be denominators, but in that case we call it the LCD. You can find the GCF of two whole numbers that happen to be the numerator and denominator of a fraction, and that will let you know whether the fraction can be simplified.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
You need at least two numbers to find an LCM.Two or more numbers are needed to find the Lcm
The LCD of two fractions is the same as the LCM of their denominators.
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
You need at least two numbers to find an LCM. And they need to be whole numbers, not fractions.
When adding unlike fractions, find the LCM of the denominators and convert them to it.
The LCM refers to whole numbers, not fractions.
When you are adding or subtracting fractions with unlike denominators, you need to find a least common denominator, or LCD. The process is the same as finding an LCM between two integers.
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
Finding the LCM will help you when you need to add and subtract fractions.
Finding an LCM will help when you want to add and subtract fractions.
When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.
We use the LCM to find the least common denominator of unlike fractions.
Finding the LCM helps in the process of adding and subtracting unlike fractions.
