Q. What is the least common multiple of

6

and

10

?

\newline

\operatorname{lcm}(6,10)=

Identify Prime Factorization: Identify the prime factorization of $6$ . Prime factorization of $6$ : $2 \times 3$
Find Distinct Prime Factors: Identify the prime factorization of $10$ . Prime factorization of $10$ : $2 \times 5$
Choose Highest Power: Identify all the distinct prime factors from the prime factorization of the two numbers. $\newline$ Distinct prime factors: $2$ , $3$ , $5$
Multiply Highest Powers: For each distinct prime factor, choose the highest power of it that appears in the prime factorization of either number. $\newline$ For $2$ : The highest power in the factorizations is $2^1$ (as it appears in both $6$ and $10$ ). $\newline$ For $3$ : The highest power in the factorizations is $3^1$ (as it appears in $6$ ). $\newline$ For $5$ : The highest power in the factorizations is $5^1$ (as it appears in $10$ ).
Find Least Common Multiple: Multiply these highest powers together to find the least common multiple (LCM). $\newline$ Multiply $2^1$ , $3^1$ , and $5^1$ to find the LCM. $\newline$ $2 \times 3 \times 5 = 30$ $\newline$ LCM of $6$ and $10$ is $30$ .
