LCM of 16 and 24
The Least common multiple (LCM) is the smallest number that is divisible by the numbers 16 and 24. The LCM can be found using the listing multiples method, the prime factorization and/or division methods. LCM helps to solve problems with fractions and scenarios like scheduling or aligning repeating cycle of events.
What is the LCM of 16 and 24?
The LCM of 16 and 24 is the smallest positive integer, a multiple of both numbers. By finding the LCM, we can simplify the arithmetic operations with fractions to equate the denominators.
How to find the LCM of 16 and 24?
There are various methods to find the LCM, Listing method, prime factorization method and division method are explained below;
LCM of 16 and 24 using the Listing multiples method
The LCM of 16 and 24 can be found using the following steps;
Step 1: Write down the multiples of each number:
Multiples of 16 = 16,32,48,64,…
Multiples of 24= 24,48,72…
Step 2: Ascertain the smallest multiple from the listed multiples of 16 and 24.
The LCM of 16 and 24 = 48
LCM of 16 and 24 using the Prime Factorization
The prime factors of each number are written, and then the highest power of the prime factors is multiplied to get the LCM.
Step 1: Find the prime factors of the numbers:
Prime factorization of 16 = 2×2×2×2×2
Prime factorization of 24 = 2×2×2×3
Step 2: Multiply the highest power of each factor ascertained to get the LCM:
LCM (16,24) = 2×2×2×3×2= 48
LCM of 16 and 24 using the Division Method
The Division Method involves simultaneously dividing the numbers by their prime factors and multiplying the divisors to get the LCM.
Step 1:Write down the numbers in a row;
Step 2:A prime integer that is evenly divisible into at least one of the provided numbers should be used to divide the row of numbers. Continue dividing the numbers until the last row of the results is ‘1’ and bring down the numbers not divisible by the previously chosen prime number.
Step 3:The LCM of the numbers is the product of the prime numbers in the first column, i.e,
2×2×2×2×3 = 48
LCM (16,24)=48
