45 The least common multiple is 45 3 x 15 45 9 x 5 45 15 x 3 45 The least common multiple LCM is the lowest multiple that is found in all of the numbers that are in your question The lowest common multiple LCM of numbers a and b can be calculated as lcm a b a b gcd a b where gcd is the greatedt common divisor In the given example the greatest common divisor gcd is 1 so the lowest common
Explanation First realise that you do not need to consider the 3 at all It is a factor of 9 so any multiple 9 is a factor of 3 Second Notice that 4 and 9 do not have any common factor so the LCM has to have all the factors of 4 and 9 Look at the product of the prime factors LCM 3 3 2 2 36 EZ as pi Jun 25 2017 LCM 2 2 3 5 11 660 Explanation 5 and 11 are both prime and share no common factors The prime factors of 12 are 2 2 3 There are no common factors between any of these numbers so the LCM will consist of all of their factors LCM 2 2 3 5 11 660 11 and 12 are consecutive numbers and

Explanation Start with the largest figure In this case that is 12 You know that the LCM has to be some multiple of 12 so start considering the multiples of 12 one at a time 12 1 12 doesn t work because 9 doesn t go into 12 evenly even though 4 does 12 2 24 isn t it either because 9 doesn t go into 24 Help 45 First we need to write out the prime factors of 9 and 15 9 3xx3 15 3xx5 Now we group them together 9 3xx3 15 3 xx 5 Next we take the largest groups of each number 9 has two 3s while 15 has 1 5 We multiply the largest groups together LCM 9 15 3xx3xx5 45 45 15 3 45 9 5
