What is the LCM of 3,4, and 5?

its 60

3 multiplied by 20
4 multiplied by 15
5 multiplied by 12

Place the prime factors in a column, and any common factors in the same column. 3 and 5 are already in their prime factors (as they're prime), but 4 = 2 x 2.

3
. . 5
. . . . 2 x 2

So the LCM is

3 x 5 x 2 x 2
60

3 = 3
4 = 2 x 2
5 = 5
-----------------
The LCM of 3 , 4 , 5 is:
2 x 2 x 3 x 5
= 60

60

Hi,
I love an-sering these questions!
So I will be glad to help you out there
Is it OK if I explain it?

3 ,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60

4 ,8,12,16,20,24,28,32,36,40,44,48,52,56,60

5 ,5,10,15,20,25,30,35,40,45,50,55,60

OK do you see the number they all have in common?
Don't be fooled when to of them have the same number, OK lets see the number they both have in common is 60
OK well I hope you get an A
Good luck
Take care

3*4*5 = 60

this would be 3*4*5 = 60
