Which pair of numbers has a least common multiple of 30? 2 and 10 3 and 15 6 and 9 6 and 15

6 and 15

3 and 15

Step-by-step explanation:

the least common multiple is the smallest number that is entirely divisible by both numbers

multiples of 2 = 2 , 4 , 6 , 8 , 10

multiples of 10 = 10 20, 30

lcm = 10  

multiples of 3 = 3 6 9 15 18 21 24 27 30

multiples of 15 = 15, 30

lcm = 30

step-by-step explanation:

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set
