Find Out the LCM of 9 and 15 with This Simple Math Trick - postfix
Who is this topic relevant for?
Finding the LCM of two numbers involves identifying the prime factors of each number and then multiplying the highest power of each common prime factor. To find the LCM of 9 and 15, we need to identify their prime factors. The prime factorization of 9 is 3^2, and the prime factorization of 15 is 3 x 5. Since both numbers have a common prime factor of 3, we multiply the highest power of 3 (which is 3^2) by the remaining prime factor of 15 (which is 5).
To find the LCM of two numbers, identify their prime factors and multiply the highest power of each common prime factor.
