Answer 2

Answer: LCM(30,75)=150

Step-by-step explanation:

Using Factoring:

Multiples of 30: 30,60,90,120,150,180,210

Multiples of 75: 75,150,225

The smallest common (all numbers share it) multiple is highlighted.

Thus, LCM(30,75)=150.

Alternatively, the least common multiple can be found as the product of numbers divided by the greatest common divisor of the numbers:

LCM(a,b)= a⋅b

           GCD(a,b).

Since GCD(30,75)=15  

then LCM(30,75)  then LCM(30,75)  = 2250 = 150

                                              15                15
