FAQ’s on LCM of 10 and 15

What is the Least Common Multiple (LCM) of 10 and 15?

The LCM of 10 and 15 is 30.

How is the LCM calculated for 10 and 15?

The LCM is determined by finding the prime factorization of each number and then multiplying the highest powers of all prime factors. For 10 and 15, the prime factorization is 2 × 5 and 3 × 5, respectively. The LCM is then obtained by taking the highest power of each prime factor, resulting in 2 × 3 × 5 = 30.

Can the LCM of 10 and 15 be smaller than both numbers?

No, the LCM is always equal to or greater than the given numbers. In the case of 10 and 15, the LCM (30) is greater than both 10 and 15.

Are there alternative methods to find the LCM of 10 and 15?

Yes, besides prime factorization, methods such as listing multiples or using the ladder method can also be employed to find the LCM of 10 and 15.

Why is finding the LCM important?

Finding the LCM is essential in various mathematical operations, such as adding or subtracting fractions, solving equations, and working with different units of measurement.

If the LCM of 10 and 15 is 30, what are the common multiples?
