LCM of 10 and 16
Least Common Multiple (LCM) is the smallest positive integer that is divisible by both 10 and 16. By learning the following tricks, you can learn the LCM of 10 and 16 easily.
What Is the LCM of 10 and 16?
The LCM of 10 and 16 is 80. How did we get to this answer, though? That’s what we’re going to learn. We also see how we can find the LCM of 2 or more numbers in different ways.
How to find the LCM of 10 and 16?
We have already read about how you can approach finding the LCM of 2 or more numbers. Here is a list of those methods which make it easy to find the LCMs:
Method 1: Listing of Multiples
Method 2: Prime Factorization
Method 3: Division Method
Now let us delve further into these three methods and how it benefits us.
LCM of 10 and 16 Using Listing of Multiples Method
In this method, we will list all the multiples of 10 and 16. Then we will try to find a multiple that is present in both numbers.
For example,
Multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100,…
Multiples of 16:
16,32,48,64,80,96,112,128,144,160,…
The LCM of 10 and 16 is 80. 80 is the smallest number which can be divisible by both 10 and 16.
LCM of 10 and 16 Using Prime Factorization
To find the LCM of 10 and 16 using the prime factorization method, we need to find out the prime factors of both the numbers. Then multiply the highest powers of the factors to get the LCM.
Prime Factors of 10 are: 21 × 51.
Prime Factors of 16 are: 24.
Multiply the highest power of both the factors: 24 × 51 = 2 × 2 × 2 × 2 × 5 = 80
Therefore, the LCM of 10 and 16 is 80.
LCM of 10 and 16 Using Division Method
To calculate the LCM using the division method. We will divide the given numbers with their prime numbers. The prime numbers should at least divide any one of the given numbers. Divide the numbers till the remainder becomes 1. By multiplying the prime factors, one can get LCM.
For finding the LCM of 10 and 16 we will use the following method.
By multiplying the prime divisors from the table, we will get the LCM of 10 and 16.
2 × 2 × 2 × 2 × 5 = 80. The LCM of 10 and 16 is 80
