Answer 2

Answer:

40

Step-by-step explanation:

$\red{\bigstar}$ LCM of 5 and 8 by Prime Factorization:

Prime factorization of 5 and 8 is (5) = $5^1$ and (2 × 2 × 2) = $2^3$ respectively.

LCM of 5 and 8 can be obtained by multiplying prime factors raised to their respective highest power, i.e. $2^3$ × $5^1$ = 40.

Hence, the LCM of 5 and 8 by prime factorization is 40.
