Answer 2

Answer:

HCF(46,51) = 1

LCM(46,51) = 2346

Step-by-step explanation:

Prime Factorisation of 46

$\begin{array}{r | l} 2&46\\\cline{1-2}23&23 \\\cline{1-2}&1\end{arry}$

46 = 2 × 23 × 1

Prime Factorisation of 51

$\begin{array}{r | l} 3&51\\\cline{1-2}17&17 \\\cline{1-2}&1\end{arry}$

51 = 3 × 17 × 1

(i) Finding HCF of 46 and 51

We don't find any common factor between 46 and 51 so the HCF of 46 and 51 is 1.

∴ HCF(46,51) = 1

(ii) Finding LCM of 46 and 51

As they don't have any common factor between them so the LCM is the product of the numbers.

LCM(46,51) = 46 × 51 = 2346

∴ LCM(46,51) = 2346
