LCM of 2 and 10
The smallest number that should also be a positive number, and evenly divide both the numbers, is known as the least common factor. LCM is very important for solving problems, especially fractions, scheduling events etc.
What is the LCM of 2 and 10
The LCM of 2 and 10 is the lowest number that divides both 2 and 10 without leaving any remainder. The LCM of 2 and 10 is 10.
How to find the LCM of 2 and 10?
The LCM of 2 and 10 can be found by the following methods like division method, listing multiples, prime factorization.
LCM of 2 and 10 using Division method:
In the division method, we divide both the numbers by the lowest possible number until we get 1 for both numbers.
2 divides 2, leaving 1
5 divides 10, leaving 1
LCM = 2 × 5= 10.
LCM of 2 and 10 using Listing multiples:
We write the multiples of both numbers till we find the common one.
Multiples of 2: 2, 4, 6, 8, 10, 12, …
Multiples of 10: 10, 20, 30, …
The common multiple is 10. So, the LCM of 2 and 10 is 10.
LCM of 2 and 10 using prime factorization:
We part each number into divisors and select the highest powers of all the prime factors.
2= 2
10= 2 × 5
LCM = 2 × 5= 10.
Common Mistakes and How to Avoid Them in LCM of 2 and 10
While solving problems on LCM, children are likely to make common mistakes, here are a few mistakes and how to avoid them.
Mistake 1
Not including the prime factors with the right ones.
Children sometimes get confused and do not include the prime factors, instead of writing 9=3×3 they write 9=3×1. Students should always break numbers into prime numbers.
LCM of 2 and 10 Examples
Problem 1
Find the LCM of 2 and 10.
The LCM of 2 and 10 is 10.
Explanation
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 10
Multiples of 10: 10, 20, 10…
The common multiple is 10. So, the LCM of 2 and 10 is 10.
Problem 2
Solve the following expression using LCM of 2 and 10: 3/2 + 1/10
When we solve the equation by using the LCM of 2 and 10, the value we get is 8/5.
Explanation
LCM(2,10)=10
3/2 = 15/10 , 1/10=110
Add the fractions:
15/10 + 1/10 = 16/ 10=8 / 5
Problem 3
Simplify the expression: x/2 + x/10 = 12
The value of x is 20.
Explanation
LCM (2,10) =10
5x/10 + x/10 =12
5x+x/10=12
6x= 12 × 10
6x = 120
x=20
