Question

What is the full form of HCF and LCM?

Answer 1

H.C.F => highest common factor...it is a largest number that divides exactly into two or more numbers.....L.C.M=>least common multiple . lcm of 2 or more numbers is the smallest number that divides both the numbers ...

Answer 2

Step-by-step explanation:

LCM (Least Common Multiple): A least number which is divisible by all the each of the given numbers is called a least common multiple.

Example: Consider the numbers 4, 12, 15.

LCM of the three is given in the image below:

$L C M=2 \times 3 \times 3 \times 2 \times 5=180$

HCF (Highest Common Factor): A largest number which divides each of the given numbers is called a highest common factor or greatest common divisor.

Example: Consider the same set of numbers 4, 12, 18.

HCF is given in the image below:

$4=2 \times 2 ; 12=2 \times 2 \times 3 ; 18=2 \times 3 \times 3$

$H C F=2$
