what is the lcm of 6 and 9 LCM of 6 and 9 2 x 3 x 3 18 Therefore the LCM of 6 and 9 is 18 Method 2 Using the Divisibility Rule The divisibility rule for finding the LCM of two numbers involves repeatedly finding multiples of the larger number until we find a multiple that is divisible by the smaller number Here s how we can use this method to find the LCM of 6
If we do we have to make sure that there isn t any other number lower than that that 6 and 9 go into First 5 Multiples of 6 6 12 color blue 18 24 30 First 5 Multiples of 9 9 color blue 18 27 36 45 There isn t any number before 18 that 6 and 9 both go into so 18 is the LCM of 6 and 9 Now The LCM can also be found as the product of the numbers divided by their greatest common factor From the above list of factors we know that 3 is a factor common to both numbers also the greatest common factor So the LCM is LCM 9 6 9 6 GCF 9 6 54 3 18

36 One way we can use is prime factorisation We factorise 4 6 and 9 4 2 2 6 2 3 9 3 3 Once we have this we use the highest of each prime number So in this case we have the 2 2 and 3 3 as our highest of those to primes Next all we need to do is times those together 2 2 4 3 3 9 4 9 36 36 is the LCM of 4 6 and 9 72 To find the lcm you have to break each number into its prime factors and then multiply the different ones with the highest recurrence 8 2 2 2 9 3 3 6 2 3 We have the prime number 2 and 3 occurring so we have find the number that has the most two s and the most three s Since 8 has three two s the most and 9 has two three s the most three s we just

The LCM of the numbers 3 6 and 9 is 18 Step by step explanation The least common multiple LCM of two or more non zero whole numbers is the smallest whole number that is divisible by each of those numbers In other words the LCM is the smallest number that all of the numbers divide into evenly To find the least common multiple LCM of 6 and 9 we can list their multiples and look for the smallest common multiple The first 5 multiples of 6 are 6 12 18 24 30 The first 5 multiples of 9 are 9 18 27 36 45 From these lists we can see that the smallest common multiple of 6 and 9 is 18 Therefore the correct answer is B 18
