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.

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.
