How to find the LCM of 5 and 15

The LCM of 5 and 15 is 15. We can find the LCM using the Listing multiples method, the prime factorization method and the long division method. These are explained below.

LCM of 5 and 15 using the Listing Multiples Method

Step 1: Write down the multiples of the numbers. Don’t stop too early.

— Multiples of 5 = 5,10,15,20,25,30,…

— Multiples of 15 = 15,15,45,60,75,…

Step 1: Find the smallest number common between the written multiples of 5, 15.

— The smallest common multiple is 15

Thus, LCM(5,15) = 15

LCM of 5 and 15 using the Prime Factorization Method

Step 1: factorize the numbers into its prime factors

5 = 5×1

15 = 5×3

Step 2: find the highest powers of the factors of 5 and 15

Step 2: Multiply the highest powers

LCM(5,15) = 15

LCM of 5 and 15 using the Division Method

Write the numbers 5,15 in a row

Divide them by their common prime factors, if there is one

Carry forward the numbers that are left undivided by the previously chosen factor

Continue dividing until the remainder is ‘1’

Multiply the divisors to find the LCM

LCM(5,15) = 15
