The least common multiple of 45 and 25 is 225.The least common multiple of 25 , 45 = 225
First break the numbers down into their prime factors:9 = 3215 = 3 x 55 = 5The LCM is the product of all the primes in each list. However if the number occurs in list twice it is only counted once.So LCM of 9, 15 and 5 = 3 x 3 x 5 = 45An example: studymaths.co.uk/keytopics/hcfandlcm.htmllcm(5, 9, 15) = 45.5 = 59 = 3^215 = 3 x 5lcm = 3^2 x 5 = 4545
To find the least common multiple (LCM) of 45, 50, and 60, we first need to find the prime factorization of each number. 45 = 3 x 3 x 5 50 = 2 x 5 x 5 60 = 2 x 2 x 3 x 5 Then, we take the highest power of each prime factor that appears in any of the factorizations. So, LCM(45, 50, 60) = 2^2 x 3^2 x 5^2 = 900. Therefore, the LCM of 45, 50, and 60 is 900.
