a.20 b.30 c.60 d.150​

Answer 1

Answer:

B. 30

Step-by-Step Explanation:

The LCM is the smallest positive number that the entirety of the numbers partition into equally.  

1. Rundown the prime variables of each number.  

2. Duplicate each factor the best number of times it happens in either number.  

Since 3 has no components other than 1 and 3  

3 is a prime number  

Since 5 has no components other than 1 and 5  

5 is a prime number  

10 has components of 2 and 5  

The LCM of 3, 5, 10 is the aftereffect of increasing all prime factors the best number of times they happen in either number.  

The LCM of 3, 5, 10 is 2⋅3⋅5 = 30
