what is the least common multiple of 5 and 10?

Explanation:

Step1: Prime - factorize the numbers

$5 = 5$; $10=2\times5$

Step2: Determine LCM

The LCM takes the highest power of each prime factor. Here, prime factors are 2 and 5. For 2, the highest power is 1 (from 10), and for 5, the highest power is 1. So, $LCM(5,10)=2\times5 = 10$

Answer:

10
