Question

LCM of 18,24,36

Answer 1

What's LCM?

Answer 2

Least common multiple

Answer 3

Oh okay.

Answer 4

to find the answer all you need to do is find out what all 3 three numbers can go into the same number and the lowest one is your lcm

Answer 5

multiples of 18 are 18,36,54,72,90

do this for 24 and 36 too and see which is the lowest number that is in all 3 lists

Answer 6

or to make a long story of it
Factor into prime numbers
18 = 2 * 3 * 3
24 = 2 * 2* 2 * 3
36 = 2 * 2 * 3 * 3
A two and a three are common to all 3 equations so
LCM = 6

Answer 7

6 is not the answer

Answer 8

you want the union of the sets, not the intersection .. intersection is the gcd

Answer 9

6 = 2 3
9 = 3 3
---------
3 is the intersection and the gcd


6 = 2 3
9 = 3 3
---------
2 3 3 is the union and the lcm

Answer 10

Wow - guess I need to learn about LCM. :-(

Answer 11

another way to see it is:

lcm(a,b) = a*b/gcd(a,b)

Answer 12

18 = 2 3 3
24 = 2 3 4
36 = 2 2 3 3
--------------
lcm: 2 2 3 3 4

Answer 13

i used 4 instead of 2 2 lol

Answer 14

18 = 2 3 3
24 = 2 2 2 3
36 = 2 2 3 3
--------------
