How do you solve the ladder method?
Youtube quote: We have all prime numbers so we make another L. Again the smallest prime number is 2. So we divide 2 by into 12 to get 6. Right by 2 into 18 to get 9. Again we make the L.
How do you find the LCM and HCF using the ladder method?

How to Find LCM by Listing Multiples
- List the multiples of each number until at least one of the multiples appears on all lists.
- Find the smallest number that is on all of the lists.
- This number is the LCM.
How do you find the LCM and GCF?
For example, the LCM of 5 and 6 can be found by simply listing the multiples of 5 and 6, and then identifying the lowest multiple shared by both numbers. 30 is the LCM. Similarly, the GCF can be found by listing the factors of each number, and then identifying the greatest factor that is shared.
How do you find the LCM of 24 and 36?
The LCM of 24 and 36 is 72. To find the least common multiple of 24 and 36, we need to find the multiples of 24 and 36 (multiples of 24 = 24, 48, 72, 96; multiples of 36 = 36, 72, 108, 144) and choose the smallest multiple that is exactly divisible by 24 and 36, i.e., 72.
What is LCM 48?
The LCM of 48 and 64 is 192. To find the least common multiple (LCM) of 48 and 64, we need to find the multiples of 48 and 64 (multiples of 48 = 48, 96, 144, 192; multiples of 64 = 64, 128, 192, 256) and choose the smallest multiple that is exactly divisible by 48 and 64, i.e., 192.
