What is the LCM of 8 and 12?

The first multiple that 8 and 12 have in common is 24. Notice that 48 is also a common multiple; however, 24 is the smallest number that they have in common. This makes it the least common multiple.

What is the LCM of 30 and 45?

What is HCF of a number?

The H.C.F. defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor. To find H.C.F. and L.C.M.

What is HCF of two numbers?

HCF of two numbers is the highest common number, which is available in both the numbers. … Sometimes, it is also called the greatest common factor (GCF) or greatest common divisor (GCD). For example, the HCF of 2 and 4 is 2, because 2 is the number which is common to both 2 and 4.

What is the easiest way to find LCM?

How to Find the LCM – FAST!!!Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6.Step 2) Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide. Choose 18. … Step 3) Take that answer and multiply it by the other number. … Step 4) Celebrate …

What is the LCM for 15 and 10?

Least common multiple (LCM) of 10 and 15 is 30.

What is the LCM of 8 and 6?

The LCM for 6 and 8 = 24 because this is the first multiple they have in common.

What is the LCM of 3 and 4?

The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of. Like the LCM of 3 and 4 is 12, because 12 is the smallest number that 3 and 4 are both factors for.

What is the formula for the LCM?

In simple words, the smallest positive number that is a multiple of two or more numbers is the LCM of those two numbers….Formula of L.C.M.Formulas To Calculate LCML.C.M formula for any two numbersL.C.M. = \frac{a\times b}{gcd\left(a,b\right)}1 more row

What is HCF formula?

Greatest Common Measure(GCM) and Greatest Common Divisor(GCD) are the other terms used to refer HCF. Example : HCF of 60 and 75 = 15 because 15 is the highest number which divides both 60 and 75 exactly. We can find out HCF using prime factorization method or by dividing the numbers or division method.

What is the LCM of 24 and 36?

Explanation: The LCM of 24 and 36 is the smallest positive integer that divides the numbers 24 and 36 without a remainder. If you just want to know what is the least common multiple of 24 and 36, it is 72. Usually, this is written as.

How many types of HCF are there?

In short, the Highest Common Factor is expressed as H.C.F. Finding H.C.F. There are three methods of finding H.C.F. of two or more numbers.

What is the LCM of two numbers?
