I can't find the LCM of 30 and 48. Help please!!
To find the lowest common multiple (LCM) of two or more numbers, list the multiples of the larger number and stop when you find a multiple of the other number. This is the LCM.
Multiples of 48: 48, 96, 144, 192, 240, 288, 336, etc.
Which of these numbers does 30 go into evenly?
The LCM is 240. To find their LCM all you need to do is divide the answers by prime numbers until you are left with either a 1 or a prime number which cannot be divided more.
In the case of 30 you have 2,3,5.
In the case of 48 you have 2,3,2,2,2.
Then write like numbers beneath each other like this:
30= 2 x 3 x 5
48= 2 x 3 x 2 x 2 x 2
The first 3 and 2 are common therefore we write them once in the next step:
LCM = 2 x 3 x 5 x 2 x 2 x 2
therefore LCM = 240
All I did was multiply all the different numbers but those numbers which were common were multiplied once. Hope that I helped you and that you understood the method!
multiples of 250
Of course! To find the Least Common Multiple (LCM) of two numbers, you need to find the smallest multiple that is divisible by both numbers simultaneously.
To find the LCM of 30 and 48, you can use multiple methods. One way is to list the multiples of each number and find the smallest common multiple.
Let's start by finding the multiples of 30: multiply 30 by 1, 2, 3, and so on until you find a common multiple with 48. The multiples of 30 are: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, and so on.
Next, let's find the multiples of 48: multiply 48 by 1, 2, 3, and so on until you find a common multiple with 30. The multiples of 48 are: 48, 96, 144, 192, 240, 288, 336, 384, and so on.
By comparing the two lists, you can see that the smallest common multiple is 240. Therefore, the LCM of 30 and 48 is 240.
