__LCM AND HCF OF TWO NUMBERS (HIGH SCHOOL MATHS VIDEOS IN TELUGU)__

###
A COMMON MULTIPLE__ __is a number that is a multiple of two or more numbers.
The common__ __multiples of 3 and 4 are 0, 12, 24, ...__.
__

**The LEAST COMMON MULTIPLE (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.**###
**Multiples of 3:**

###
**0 ,3, 6, 9, 12,15, 18, 21, 24....**

###
** Multiples of 4:**

###
**0, 4,8, 12,16,20,24, 28.... **** **

###
**The LCM of 3 and 4 is 12.**

**The LCM of 3 and 4 is 12.**

###
**Highest Common Factor(HCF)**

**Highest Common Factor(HCF)**

### Highest Common Factor(HCF) of two or more numbers is the greatest number which divides each of them exactly.

### 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.**
