Question

what do u mean by HCF and LCM? give examples
​

Answer 1

Answer:

HCF (Highest Common Factor)

As the rules of mathematics dictate, the greatest common divisor or the gcd of two or more positive integers happens to be the largest positive integer that divides the numbers without leaving a remainder. For example, take 8 and 12. The H.C.F. of 8 and 12 will be 4 because the highest number that can divide both 8 and 12 is 4.

LCM (Least Common Multiple)

In arithmetic, the least common multiple or LCM of two numbers say a and b, is denoted as LCM (a,b). And the LCM is the smallest or least positive integer that is divisible by both a and b. For example, let us take two positive integers 4 and 6.

Multiples of 4 are: 4,8,12,16,20,24…

Multiples of 6 are: 6,12,18,24….

The common multiples for 4 and 6 are 12,24,36,48…and so on. The least common multiple in that lot would be 12.

Step-by-step explanation:

Answer 2

Answer:

HCF- Highest Common Factor

eg: HCF of 12 and 16

=> 12= 2×2×3

    16= 2×2×2×2

HCF= 2×2 = 4

LCM: Least Common Multiple

eg: LCM of 12 and 16

⇒ 12 = 2×2×3

   16 = 2×2×2×2

LCM = 2×2×2×2×3 = 48

HOPE YOU UNDERSTOOD HAT HCF AND LCM MEANS.
