The LCM is: 6,930
lcm(8, 9, 24) = 72 Using prime factorisation: 8 = 2³ 9 = 3² 24 = 2³ x 3 lcm = 2³ x 3² = 72
To find the least common multiple (LCM) of 9, 45, and 81, we first need to factorize each number. The prime factorization of 9 is 3^2, 45 is 3^2 * 5, and 81 is 3^4. The LCM is the product of the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 9, 45, and 81 is 3^4 * 5, which equals 405.
The LCM of 2, 8, and 9 is 72
The LCM is 18.
18 is the LCM of 2, 3, and 9
lcm(8, 9) = 72. 8 = 2^3 9 = 3^2 lcm = 2^3 x 3^2 = 72
The LCM is 90.
The LCM is 126.
The LCM is 18.
The LCM is: 18
it is NOT 3
9 is a factor of 27 so need not be considered further. 27 = 3*3*3 and 24 = 2*2*2*3 so LCM is 2*2*2*3*3*3 = 216
The LCM of 6, 9, 4, and 2 is 36. The LCM must include at least 2·2 to be a multiple of 4 and 3·3 to be a multiple of 9. 2·2·3·3 = 36 = which is also a multiple of both 2 and 6.
lcm(6, 12, 9, 15) = 180 6 = 2 x 3 12 = 2^2 x 3 9 = 3^2 15 = 3 x 5 lcm = 2^2 x 3^2 x 5 = 180
The Least Common Multiple (LCM) for 2 3 9 is 18.
