Question

What is the full form of math and
How do we find LCM

Answer 1

$\underline{\boxed{\sf{\pink{LCM : Least \ Common \ Multiple}}}}$

• The Least Common Multiple of two or more given numbers is the smallest number that is a common multiple of the given numbers Like The LCM of 6 and 9 is 18 .

• The LCM of two or more numbers is always greater than or equal to any of the numbers.

• The LCM of two prime numbers or co-prime numbers is equal to the product of the numbers.

• The HCF of two or more given numbers is always a factor of their LCM.

• If one number is a multiple of other then the LCM of these two numbers is the larger number.

$\large{\star}$ There are three methods to find LCM of numbers

1.  $\sf{Common \ Multiple \ Method}$

2. $\sf{Prime \ Factorisation \ Method}$

3. $\sf{Division \ Method}$  

$\rule{200}2$

Answer 2

$\huge \bf \underline \red{Question}$

$\sf{LCM}$

$\bf{ \boxed{ \green{ \tt{least \: common \: multiple \: }}}}$

_________________________________

$\bf{ \boxed{ \red{ \tt{what \: is \: LCM \: }}}}$

• LCM stands for least common multiple

• LCM is the smallest number other than 0 that is multiple of 2 or more whole number

• the LCM of relative prime numbers is the product of those numbers

• The least common multiple is otherwise known as the lowest common multiple.

• The LCM of two prime numbers or co-prime numbers is equal to the product of the numbers.

• The HCF of two or more given numbers is always a factor of their LCM.

LCM are three methods there are:

➷Common Multiple Method

➷Prime Factorisation Method

➷Division Method

How to find LCM

• To find the LCM we find the prime factor of given number

• we consider common prime factor only

Example

Find the LCM of 12 and 16 .

First we find the prime factor of the given numbers

then

$\sf{12 = 2 \times 2 \times 3}$

$\sf{8 = 2 \times 2 \ \times 2}$

$\sf{3 \times 2 \times 2 \times 2 = 24}$

$\sf{lcm \: of \: 12 \: and \: 8 \: is \: 24}$

• We can also find the L.C.M. of the given numbers by dividing all the numbers at the same time by a number that divides at least two of the given numbers.

What is multiple?

• a multiple is a numner which can be divided by another number without a reminder

i hope it's help uh
