Prime factorization

Example: 30 and 42

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

Can the LCM be 1?

No, as LCM deals with two or more numbers. The only way for it to be one is if you only had 1. But you can't find the LCM of a single number, there must be two or more. So, there is no LCM of 1.


What are the LCM of 36 and 120?

360. The easiest way to find LCM is to write down a few multiples of the larger number and then write multiples of the smaller number to catch up and see if any match. If none do, continue with the larger number and follow with the smaller.


How do you find the LCM of a number using a list?

You can only find the LCM of two or more numbers. One way to do this is by listing the multiples of each number until you reach a number that appears on both lists. Example 30 and 42 30, 60, 90, 120, 150, 180, 210 42, 84, 126, 168, 210 210 is the LCM of 30 and 42


What do you do when you write 2 given numbers whose LCM if 24 is the number?

The easiest way is to write the number and a factor of the number. 12 and 24 have an LCM of 24.


What is the LCM of 2 and 4 and 5 and 6?

easiest way take 6 and go through its multiples until you find a number that is divisible by all four numbers, 6,12,18 etc in this case 60 is the answer


Least common multiple for 7 and 17?

7 and 17 are both primes numbers. The means that to find the LCM we need multiply them. The LCM of 7 and 17 is 7x17 which is 119. If two numbers are prime, then they are also relatively prime and in general the way to find the LCM of relatively prime number is to multiply them together.


Can a LCM be one?

Yes, if the the number you are finding the LCM of is 1. But usually, LCM involves two or more numbers. While finding the LCM of one number is uncommon and technically an incorrect practice, it is possible.


Is the least common multiple of two prime numbers their product?

Yes, always. This is the easiest way to find the LCM of two (or indeed any number of) primes.
